note 112912 added to function.hex2bin

Since this function only exists from PHP 5.4 and above, the following works as a drop-in replacement for older versions of PHP. It is a little modified version of the code provided by @Johnson. It seems to works pretty fine. <?php if ( !function_exists( 'hex2bin' ) ) { function hex2bin( $str ) { $sbin = ""; $len = strlen( $str ); for ( $i = 0; $i < $len; $i += 2 ) { $sbin .= pack( "H*", substr( $str, $i, 2 ) ); } return $sbin; } } ?> ---- Server IP: 69.147.83.199 Probable Submitter: 212.29.41.170 ---- Manual Page -- http://php.net/manual/en/function.hex2bin.php Edit -- https://master.php.net/note/edit/112912 Del: integrated -- https://master.php.net/note/delete/112912/integrated Del: useless -- https://master.php.net/note/delete/112912/useless Del: bad code -- https://master.php.net/note/delete/112912/bad+code Del: spam -- https://master.php.net/note/delete/112912/spam Del: non-english -- https://master.php.net/note/delete/112912/non-english Del: in docs -- https://master.php.net/note/delete/112912/in+docs Del: other reasons-- https://master.php.net/note/delete/112912 Reject -- https://master.php.net/note/reject/112912 Search -- https://master.php.net/manage/user-notes.php
