⚠️ Important: Development Environment Only
This plugin is designed for development environments like LocalWP, XAMPP, or self-hosted servers. It will not work on most managed hosting providers (WP Engine, Kinsta, SiteGround, etc.) due to security restrictions that disable the <code>exec()</code> function and limit access to PHP binaries.
How It Works
This plugin leverages <a href="https://github.com/squizlabs/PHP_CodeSniffer" rel="nofollow ugc">PHP_CodeSniffer</a> with the <a href="https://github.com/PHPCompatibility/PHPCompatibility" rel="nofollow ugc">PHPCompatibility</a> standard to perform deep static analysis of your PHP code.
Core Components:
<ol>
<li>Bundled Dependencies: Includes PHP_CodeSniffer and PHPCompatibility ruleset</li>
<li>Batch Processing: Scans files in configurable batches (10-100 files) to manage memory usage</li>
<li>Command Execution: Executes PHPCS via PHP’s <code>exec()</code> function with specific parameters</li>
<li>Server-Side State: Stores file lists in WordPress options to optimize AJAX requests</li>
<li>Progressive UI: Real-time batch results with stop/start controls</li>
</ol>
How to Use:
<ol>
<li>Navigate to Tools → PHP Compatibility Scanner</li>
<li>Review the System Check section to ensure your environment is compatible</li>
<li>Select the plugins and/or themes you want to scan by checking their boxes</li>
<li>Configure your scan options:
<ul>
<li>Target PHP Version: Choose the PHP version you want to test against (7.4 – 8.4)</li>
<li>Batch Size: Select how many files to process at once (default: 50 files)</li>
<li>Skip Vendor Directory: Keep checked to skip third-party dependencies</li>
</ul>
</li>
<li>Click Start Scan to begin the compatibility check</li>
<li>View results in real-time as each plugin/theme is scanned</li>
<li>Review any errors (❌) or warnings (⚠️) found in your code</li>
<li>Click on any target to expand and see detailed compatibility issues</li>
</ol>
Why It Requires Development Environments
<ul>
<li><code>exec()</code> Function: Required to run PHPCS binary – disabled on managed hosts</li>
<li>PHP Binary Access: Needs access to PHP executable – restricted on shared hosting</li>
<li>Composer Dependencies: Requires vendor directory with PHPCS installation</li>
<li>File System Access: Creates temporary files for batch processing</li>
<li>Memory/Time Limits: Long-running scans need relaxed execution limits</li>
</ul>
Supported Environments
<ul>
<li>LocalWP (recommended)</li>
<li>XAMPP/MAMP</li>
<li>Docker WordPress setups</li>
<li>Self-hosted VPS/dedicated servers</li>
<li>Development environments with shell access</li>
</ul>
Unsupported Environments
<ul>
<li>WP Engine (exec() disabled)</li>
<li>Kinsta (security restrictions)</li>
<li>SiteGround (managed hosting limitations)</li>
<li>GoDaddy Managed WordPress (function restrictions)</li>
<li>WordPress.com (no plugin uploads)</li>
<li>Most shared hosting providers</li>
</ul>
