How can encrypted PHP code be decrypted for analysis and understanding?

Encrypted PHP code can be decrypted for analysis and understanding by using a decryption key and algorithm specific to the encryption method used. One common approach is to decrypt the code using a tool or script that has the necessary decryption logic in place.

// Example code snippet for decrypting encrypted PHP code using a decryption key
$encryptedCode = "encrypted code here";
$decryptionKey = "decryption key here";

$decryptedCode = openssl_decrypt($encryptedCode, 'AES-256-CBC', $decryptionKey, 0, $decryptionKey);

eval($decryptedCode); // Execute the decrypted code
