// Example of MD5 hashing $string = "Hello World"; $hash = md5($string); echo $hash; // Outputs: b10a8db164e0754105b7a99be72e3fe5 Since MD5 is a hash function, there's no decryption function like md5_decrypt() . What people usually mean is reverse lookup or cracking MD5 hashes. Methods to "Reverse" MD5 in PHP 1. Rainbow Table Attack Precomputed tables of hash → plaintext pairs.
