ini_parse_quantity() fails to emit warning for 0x+0 #16886
Description
Description
zend_ini_consume_quantity_prefix(), when a leading zero that is not part of a base prefix is found, incorrectly returns a pointer to the first character processed, rather than to the zero. This means that ini_parse_quantity() emits no warning for invalid input that matches the regex ^\s*[+-]?0[xXoObB](?:\s+[+-]?|[+-])0\s*$, where \s is any character listed in zend_is_whitespace().
The following code:
<?php
echo ini_parse_quantity('0x 0'), "\n";
echo ini_parse_quantity('0x+0'), "\n";
echo ini_parse_quantity('0x-0'), "\n";Resulted in this output:
0
0
0
But I expected this output instead:
Warning: Invalid quantity "0x 0": no digits after base prefix, interpreting as "0" for backwards compatibility in /home/ki/Documents/Scratchpad/test_parse_quantity_prefixes.php on line 2
0
