I can also confirm that this wasn't present in php5-fpm 5.6.0~rc1+dfsg-1, it occured when I updated to php5-fpm 5.6.0~rc2+dfsg-3 Key: Host H => 72 o => 111 s => 115 t => 116 => 0 Key: User-Agent U => 85 s => 115 e => 101 r => 114 - => 45 A => 65 g => 103 e => 101 n => 110 t => 116 => 0 Key: Cache-Control C => 67 a => 97 c => 99 h => 104 e => 101 - => 45 C => 67 o => 111 n => 110 t => 116 r => 114 o => 111 l => 108 => 0 Key: Accept A => 65 c => 99 c => 99 e => 101 p => 112 t => 116 => 0 Key: Accept-Language A => 65 c => 99 c => 99 e => 101 p => 112 t => 116 - => 45 L => 76 a => 97 n => 110 g => 103 u => 117 a => 97 g => 103 e => 101 => 0 Key: Cookie C => 67 o => 111 o => 111 k => 107 i => 105 e => 101 => 0 Previous Comments: ------------------------------------------------------------------------ [2014-07-17 21:44:29] yohgaki@php.net Do you observe trailing NULL chars for all keys? ------------------------------------------------------------------------ [2014-07-17 15:00:27] herve at moulticast dot net Description: ------------ Running Debian with kernel 3.14-1-amd64 Webserver: NginX 1.6.0 PHP: 5.6.0RC2 FPM The getallheaders() method does not build a clean array. When trying to access some values via $arr['key'] it doesn't work because there is a non printable character '0' that is added at the end of the key. Test script: --------------- <?php // Working example foreach($_SERVER as $key => $value) { print('Key: '. $key . ' => ' . $value . "\n"); $key_arr = str_split($key); foreach($key_arr as $char) { print($char . ' => ' . ord($char) .' '); } print "\n"; } // Buggy example using getallheaders $hdrs = getallheaders(); foreach($hdrs as $key => $value) { print('Key: '. $key . ' => ' . $value . "\n"); $key_arr = str_split($key); foreach($key_arr as $char) { print($char . ' => ' . ord($char) .' '); } print "\n"; } ?> Expected result: ---------------- Key for header 'User-Agent' should be (in ASCII): 85 115 101 114 45 65 103 101 110 116 Actual result: -------------- Key for header 'User-Agent' is (in ASCII): 85 115 101 114 45 65 103 101 110 116 0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67642&edit=1
