Click the <code>Save All Active Plugins</code> button to create a backup of the current active plugins. Then you can quickly turn them all back on before anyone is the wiser. You can even refresh the plugin page 
(I know.. you did it on accident) without losing which plugins you deactivated.

Great tool for quickly testing for plugin compatibility issues. Click the Save All Active Plugins button to backup all active plugins.

⚠️ 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>
