   www.php-editors.com › php_manual › function

   The IV is ignored in ECB mode as this mode does not require it. You will need to have the same IV (think: starting point) both at encryption and decryption stages, otherwise your encryption will fail. It is more useful to use the mcrypt_enc_get_iv_size () function as this uses the resource returned by mcrypt_module_open ().
