hex2bin: E_WARNING is too much for odd string?

Hi all, hex2bin raises E_WARNING for odd length hex strings from PHP 5.4.1. http://jp2.php.net/manual/en/function.hex2bin.php However, just returning FALSE is easier for programmers. Current behavior requires additional length check for bad hex to prevent E_WARNING. $str = 'abZ'; if (strlen($str)%2) { // BAD hex - invalid length } else if (hex2bin($str) { // BAD hex - invalid char } Instead, it would better that hex2bin() just returns FALSE for invalid hex, IMHO. $str = 'abZ'; if (strlen($str)%2) { // BAD hex - invalid length or char } I can understand current behavior as BC. However, it would better cleanup bad spec sooner or later. PHP 5.4: Raise E_ERROR and return FALSE for invalid length. PHP 5.5: Just return FALSE. or PHP 5.4: Keep current behavior PHP 5.4: Riase E_ERROR and return FALSE for invalid length. PHP 5.5: Remove E_ERROR. Any ideas? -- Yasuo Ohgaki yohgaki@ohgaki.net
