This is a simple PHP extension for hooking eval().

• PHP 7 (recommend)
• PHP 5.6.x (untested)

• Download source code file php_eval.c
• Download PHP source code and prepare your PHP building environment (https://wiki.php.net/internals/windows/stepbystepbuild)
• Compile php_eval.c and build a DLL file with your Visual C++
• Copy the DLL file into PHP extension dir and install it by modifying php.ini
• Restart your server

Example:

<?php /* write your code in __eval() */ function __eval($code, $file) { echo "eval() @ {$file}:\n{$code}\n\n"; // you can return FALSE to prevent this eval() return false; // or you can return a string to replace $code for executing return 'echo 2;'; // or you can return nothing to executing $code next } eval('echo 1;');
