unpack

Description

unpack() from binary string into array according to format. Returns array containing unpacked elements of binary string.

unpack() works slightly different from Perl as the unpacked data is stored in an associative array. To accomplish this you have to name the different format codes and separate them by a slash /.

Example 1. unpack() example <?php $array = unpack("c2chars/nint", $binarydata); ?> The resulting array will contain the entries "chars1", "chars2" and "int".

See also pack() for an explanation of the format codes.
