If the hash functions are not available to you at the moment, and you want to future proof your code, then the code below will emulate two of the important hashing functions, they will also be automatically replaced with the faster versions if available. <?php if(!function_exists('hash_algos')) { function hash_algos() { $algo[0] = "md5"; $algo[1] = "sha1"; $algo[2] = "crc32"; return($algo); } } if(!function_exists('hash')) { function hash($algo, $data, $raw_output = 0) { if($algo == 'md5') return(md5($data)); if($algo == 'sha1') return(sha1($data)); if($algo == 'crc32') return(crc32($data)); } } ?> --was-- If the hash functions are not available to you at the moment, and you want to future proof your code, then the code below will emulate two of the important hashing functions, they will also be automatically replaced with the faster versions if available. if(!function_exists('hash_algos')) { function hash_algos() { $algo[0] = "md5"; $algo[1] = "sha1"; $algo[2] = "crc32"; return($algo); } } if(!function_exists('hash')) { function hash($algo, $data, $raw_output = 0) { if($algo == 'md5') return(md5($data)); if($algo == 'sha1') return(sha1($data)); if($algo == 'crc32') return(crc32($data)); } } http://php.net/manual/en/function.hash.php
