mcrypt_get_block_size - Gets the block size of the specified cipher

SYNOPSIS
int mcrypt_get_block_size (int $cipher)
DESCRIPTION
int mcrypt_get_block_size (string $cipher, string $mode) The first prototype is when linked against libmcrypt 2.2.x, the second when linked against libmcrypt 2.4.x or 2.5.x. mcrypt_get_block_size(3) is used to get the size of a block of the specified $cipher (in combination with an encryption mode). It is more useful to use the mcrypt_enc_get_block_size(3) function as this uses the resource returned by mcrypt_module_open(3).
PARAMETERS
o $cipher -One of the MCRYPT_ciphername constants, or the name of the algorithm as string. o $mode -One of the MCRYPT_MODE_modename constants, or one of the following strings: "ecb", "cbc", "cfb", "ofb", "nofb" or "stream".
RETURN VALUES
Gets the block size, as an integer.
EXAMPLES
Example #1 mcrypt_get_block_size(3) example This example shows how to use this function when linked against libmcrypt 2.4.x and 2.5.x. <?php echo mcrypt_get_block_size('tripledes', 'ecb'); // 8 ?>
