PHP: Export Source Code Data To Excel

So, you're looking to export your PHP source code data into an Excel spreadsheet? Awesome! This is a common task, and it's super useful for things like auditing code, generating reports, or even just making your codebase more accessible to non-developers. Let's break down how to do this in a straightforward, easy-to-understand way.

Why Export to Excel?

Before diving into the code, let's quickly cover why you might want to do this. Excel provides a familiar and versatile way to view and manipulate data. Here are a few scenarios:

Code Audits: Imagine you need to review a large codebase for specific functions or patterns. Exporting the code's structure and key elements to Excel allows auditors to easily filter, sort, and analyze the data.
Documentation: Sometimes, automatically generating documentation from your code can be a real time-saver. Excel can be an intermediary step in creating more polished documentation.
Reporting: Need to generate reports on code complexity, function usage, or other metrics? Exporting to Excel allows you to create charts and graphs to visualize this data.
Collaboration: Sharing code information with non-developers becomes much easier when it's in a format they understand.

Essentially, exporting to Excel bridges the gap between code and readily understandable data, making it a powerful tool for various tasks.

Prerequisites

Before we get started, make sure you have the following:

PHP: You'll need a working PHP environment. This could be on your local machine (using XAMPP, MAMP, or similar) or on a web server.
PHPExcel/PhpSpreadsheet Library: This library is essential for creating and manipulating Excel files in PHP. It handles all the complexities of the Excel file format, so you don't have to worry about the nitty-gritty details.
Basic PHP Knowledge: A basic understanding of PHP syntax, file handling, and arrays is helpful.

Installing PhpSpreadsheet

PhpSpreadsheet is the recommended library for working with Excel files in PHP. It's the successor to PHPExcel and offers better performance and support for newer Excel formats. You can install it using Composer, the PHP dependency manager.

Install Composer: If you don't already have Composer installed, you can download it from https://getcomposer.org/.
Install PhpSpreadsheet: Open your command line, navigate to your project directory, and run the following command:
```
composer require phpoffice/phpspreadsheet
```
This will download and install PhpSpreadsheet and its dependencies into your project's vendor directory.

The Basic Steps

Here’s a high-level overview of the process:

Read the Source Code: You'll need to read the PHP files you want to export data from. This usually involves using PHP's file handling functions like file_get_contents() or fopen().
Extract Relevant Data: Decide what data you want to extract from the code. This could be function names, class names, comments, variables, or any other information you find useful. You might use regular expressions or PHP's token_get_all() function to parse the code.
Prepare the Data for Excel: Organize the extracted data into a format suitable for Excel, typically an array where each element represents a row in the spreadsheet.
Create an Excel File: Use PhpSpreadsheet to create a new Excel file and add the data to it.
Save the Excel File: Save the generated Excel file to a location on your server.

Example: Exporting Function Names

Let's walk through a practical example: exporting all the function names from a PHP file to an Excel spreadsheet.

1. Read the Source Code

First, we need to read the contents of the PHP file. Let's say we have a file named my_functions.php:

<?php

/**
 * This is a sample function.
 */
function myFunction1($param1, $param2)
{
    // Function logic here
    return $param1 + $param2;
}

function myFunction2()
{
    // Another function
    return true;
}

?>

Here's the PHP code to read the file:

<?php
$filename = 'my_functions.php';
$fileContent = file_get_contents($filename);

if ($fileContent === false) {
    die('Could not read file: ' . $filename);
}
?>

2. Extract Function Names

Now, we need to extract the function names from the code. We can use regular expressions for this. A simple regex to find function names might look like this:

<?php
$pattern = '/function\s+([a-zA-Z0-9_]+)\s*\(/';
preg_match_all($pattern, $fileContent, $matches);

$functionNames = $matches[1];

print_r($functionNames);
?>

This code uses preg_match_all() to find all occurrences of the function keyword followed by a space, then captures the function name (which can contain letters, numbers, and underscores) until it encounters an opening parenthesis. The extracted function names are stored in the $functionNames array. The print_r() function is just for demonstration, so you can see the extracted names.

3. Prepare Data for Excel

Next, let's prepare the data for our Excel spreadsheet. We'll create an array where each element is a row containing a function name.

<?php
$excelData = [['Function Name']]; // Header row
foreach ($functionNames as $functionName) {
    $excelData[] = [$functionName];
}
?>

We start with a header row containing "Function Name". Then, we loop through the $functionNames array and add each function name as a new row in the $excelData array.

4. Create and Populate the Excel File

Now, let's use PhpSpreadsheet to create the Excel file and add the data.

<?php
require 'vendor/autoload.php'; // Include Composer's autoloader

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();

// Populate the spreadsheet with data
$sheet->fromArray($excelData);

// Auto-size columns
foreach (range('A', 'A') as $column) {
    $sheet->getColumnDimension($column)->setAutoSize(true);
}

$writer = new Xlsx($spreadsheet);
$excelFileName = 'function_names.xlsx';
$writer->save($excelFileName);

echo 'Excel file created: ' . $excelFileName;
?>

Here's what this code does:

It includes Composer's autoloader to load the PhpSpreadsheet classes.
It creates a new Spreadsheet object.
It gets the active sheet.
It uses the fromArray() method to populate the spreadsheet with the data from the $excelData array.
It automatically adjusts the column width to fit the content.
It creates an Xlsx writer to save the spreadsheet in the XLSX format.
It saves the Excel file as function_names.xlsx.
It prints a message to confirm that the file has been created.

5. Complete Code

<?php
require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$filename = 'my_functions.php';
$fileContent = file_get_contents($filename);

if ($fileContent === false) {
    die('Could not read file: ' . $filename);
}

$pattern = '/function\s+([a-zA-Z0-9_]+)\s*\(/';
preg_match_all($pattern, $fileContent, $matches);

$functionNames = $matches[1];

$excelData = [['Function Name']]; // Header row
foreach ($functionNames as $functionName) {
    $excelData[] = [$functionName];
}

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->fromArray($excelData);

foreach (range('A', 'A') as $column) {
    $sheet->getColumnDimension($column)->setAutoSize(true);
}

$writer = new Xlsx($spreadsheet);
$excelFileName = 'function_names.xlsx';
$writer->save($excelFileName);

echo 'Excel file created: ' . $excelFileName;
?>

Save this code as, for example, export_functions.php, and run it from your web server or command line. It will create an Excel file named function_names.xlsx containing the list of function names from my_functions.php.

Exporting Class Names and Methods

Expanding on the previous example, let's explore how to export class names and their methods to Excel. This is a bit more complex, as it involves identifying classes and then iterating through their methods.

1. Read the Source Code (Same as Before)

We'll use the same method as before to read the PHP source code into a string.

2. Extract Class Names and Methods

We can use PHP's token_get_all() function to parse the code into tokens. This gives us a structured representation of the code, making it easier to identify classes and methods. Let's assume you have a PHP file like this:

<?php

class MyClass
{
    public $property1;
    private $property2;

    public function myMethod1($param1)
    {
        // Method logic
    }

    private function myMethod2()
    {
        // Another method
    }
}

class AnotherClass
{
    public function anotherMethod()
    {
        // Method logic
    }
}

?>

Here's the code to extract class names and methods:

<?php
$filename = 'my_classes.php';
$fileContent = file_get_contents($filename);

if ($fileContent === false) {
    die('Could not read file: ' . $filename);
}

$tokens = token_get_all($fileContent);

$classes = [];
$currentClass = null;

foreach ($tokens as $token) {
    if (is_array($token)) {
        if ($token[0] === T_CLASS) {
            // Found a class keyword
            $currentClass = ['name' => null, 'methods' => []];
        } elseif ($token[0] === T_STRING && $currentClass !== null && $currentClass['name'] === null) {
            // Found the class name
            $currentClass['name'] = $token[1];
        } elseif ($token[0] === T_FUNCTION) {
            // Found a function keyword (potential method)
            $methodName = null;
        } elseif ($token[0] === T_STRING && isset($methodName) && $methodName === null) {
            // Found the method name
            $methodName = $token[1];
            $currentClass['methods'][] = $methodName;
        }
    } elseif ($token === '{' && $currentClass !== null) {
        // Class definition starts
        $classes[] = $currentClass;
        $currentClass = null;
        $methodName = null;
    }
}

print_r($classes);
?>

This code iterates through the tokens:

When it finds a T_CLASS token, it indicates the start of a class definition.
It then looks for the T_STRING token immediately following the T_CLASS token to get the class name.
Similarly, it identifies methods by looking for T_FUNCTION tokens followed by T_STRING tokens representing the method names.
It stores the class names and methods in the $classes array.

3. Prepare Data for Excel

Now, let's format the extracted data for Excel.

<?php
$excelData = [['Class Name', 'Methods']]; // Header row

foreach ($classes as $class) {
    $className = $class['name'];
    $methods = implode(', ', $class['methods']); // Concatenate methods into a string
    $excelData[] = [$className, $methods];
}
?>

We create a header row with "Class Name" and "Methods". Then, we loop through the $classes array and add each class and its methods as a new row in the $excelData array. We use implode() to concatenate the methods into a comma-separated string.

4. Create and Save the Excel File (Same as Before)

We can use the same code as in the previous example to create the Excel file and save the data.

5. Complete Code

<?php
require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$filename = 'my_classes.php';
$fileContent = file_get_contents($filename);

if ($fileContent === false) {
    die('Could not read file: ' . $filename);
}

$tokens = token_get_all($fileContent);

$classes = [];
$currentClass = null;

foreach ($tokens as $token) {
    if (is_array($token)) {
        if ($token[0] === T_CLASS) {
            $currentClass = ['name' => null, 'methods' => []];
        } elseif ($token[0] === T_STRING && $currentClass !== null && $currentClass['name'] === null) {
            $currentClass['name'] = $token[1];
        } elseif ($token[0] === T_FUNCTION) {
            $methodName = null;
        } elseif ($token[0] === T_STRING && isset($methodName) && $methodName === null) {
            $methodName = $token[1];
            $currentClass['methods'][] = $methodName;
        }
    } elseif ($token === '{' && $currentClass !== null) {
        $classes[] = $currentClass;
        $currentClass = null;
        $methodName = null;
    }
}

$excelData = [['Class Name', 'Methods']];

foreach ($classes as $class) {
    $className = $class['name'];
    $methods = implode(', ', $class['methods']);
    $excelData[] = [$className, $methods];
}

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->fromArray($excelData);

foreach (range('A', 'B') as $column) {
    $sheet->getColumnDimension($column)->setAutoSize(true);
}

$writer = new Xlsx($spreadsheet);
$excelFileName = 'class_methods.xlsx';
$writer->save($excelFileName);

echo 'Excel file created: ' . $excelFileName;
?>

Save this code as export_classes.php and run it. It will create an Excel file named class_methods.xlsx containing the class names and their methods.

Error Handling and Considerations

File Permissions: Ensure your PHP script has the necessary permissions to read the source code files and write the Excel file.
Memory Limits: When dealing with large codebases, you might encounter memory limit issues. Consider increasing the memory limit in your php.ini file or using techniques like streaming to process the code in smaller chunks.
Complexity: Parsing PHP code can be complex, especially when dealing with advanced language features like namespaces, traits, and closures. Regular expressions might not be sufficient for all cases. Consider using a more robust PHP parser if you need to extract complex information.
Security: Be cautious when exporting code that contains sensitive information like passwords or API keys. Ensure the Excel file is stored securely and access is restricted.

Conclusion

Exporting PHP source code data to Excel can be a valuable technique for code auditing, documentation, reporting, and collaboration. By using the PhpSpreadsheet library and PHP's file handling and parsing capabilities, you can easily extract and organize code information into a readily understandable format. Remember to handle errors, consider memory limits, and be mindful of security when working with sensitive code. With the examples provided, you should have a solid foundation to build upon and tailor the process to your specific needs. Good luck, and happy coding! Remember to always test your code and handle errors gracefully!
