Bug description:unpack("a5", "str\0") does not work as expected
Description:
------------
related bug: https://bugs.php.net/bug.php?id=39588
if unpacking from a binary string ending with any number of "\0"'s, and the
unpack string length is given, the resulted string does not have the right
length.
for example, unpack("a5", "str\0") should result in a 5-byte-long string,
but it returns a 3-byte-long instead.
Test script:
---------------
<?php
$var = "str";
$packed = pack("a5", $var); // 5 bytes long NULL-padded string
var_dump(unpack("a5", $packed));
Expected result:
----------------
array(1) {
[1]=>
string(5) "str\0\0"
}
Actual result:
--------------
array(1) {
[1]=>
string(3) "str"
}
