This is a simple function that (correctly) escapes XML entities in an UTF-8 string, including non-ASCII characters. Get code for uniord() function from the ord() function man page. <?php function xmlentities( $string ) { $j = mb_strlen( $string, 'UTF-8' ); $result = ""; for( $k = 0; $k < $j; $k++ ) { $char = mb_substr( $string, $k, 1, 'UTF-8' ); switch( $char ) { case "&": $result .= "&amp;"; break; case "\"": $result .= "&quot;"; break; case "<": $result .= "&lt;"; break; case ">": $result .= "&gt;"; break; default: $num = uniord( $char ); if( $num <= 31 || $num == 39 // "'" || $num == 96 // "`" || $num >= 127 ) $result .= "&#".$num.";"; else $result .= $char; break; } } return $result; } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 89.100.157.91 ---- Manual Page -- http://www.php.net/manual/en/function.htmlentities.php Edit -- https://master.php.net/note/edit/100726 Del: integrated -- https://master.php.net/note/delete/100726/integrated Del: useless -- https://master.php.net/note/delete/100726/useless Del: bad code -- https://master.php.net/note/delete/100726/bad+code Del: spam -- https://master.php.net/note/delete/100726/spam Del: non-english -- https://master.php.net/note/delete/100726/non-english Del: in docs -- https://master.php.net/note/delete/100726/in+docs Del: other reasons-- https://master.php.net/note/delete/100726 Reject -- https://master.php.net/note/reject/100726 Search -- https://master.php.net/manage/user-notes.php
