Decryption function in PHP returning a value of 1 (What am I doing wrong?)

[selocan222]

This is the method\[code\]public function _PRZ_decrypt_data($_salt, $_input){ return trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $_salt, $_input, MCRYPT_MODE_ECB, $this->_PRZ_get_iv()));}\[/code\]I am calling it as one of my parameters as follows\[code\]$this->_PRZ_decrypt_data($salt, base64_decode($code))\[/code\]It seems to be returning a 1 when a properly endoded value is decoded via the function.
