note 106535 added to function.htmlentities

I'm glad 5.4 has xml support, but many of us are working with older installations, some of us still have to use PHP4. If you're like me you've been frustrated with trying to use htmlentites/htmlspecial chars with xml output. I was hoping to find an option to force numeric encoding, lacking that, I have written my own xmlencode function, which I now offer: usage: $string xmlencode( $string ) it will use htmlspecialchars for the valid xml entities amp, quote, lt, gt, (apos) and return the numeric entity for all other non alpha-numeric characters. ------------------------------------------- if( !function_exists( 'xmlentities' ) ) { function xmlentities( $string ) { $not_in_list = "A-Z0-9a-z\s_-"; return preg_replace_callback( "/[^{$not_in_list}]/" , 'get_xml_entity_at_index_0' , $string ); } function get_xml_entity_at_index_0( $CHAR ) { if( !is_string( $CHAR[0] ) || ( strlen( $CHAR[0] ) > 1 ) ) { die( "function: 'get_xml_entity_at_index_0' requires data type: 'char' (single character). '{$CHAR[0]}' does not match this type." ); } switch( $CHAR[0] ) { case "'": case '"': case '&': case '<': case '>': return htmlspecialchars( $CHAR[0], ENT_QUOTES ); break; default: return numeric_entity_4_char($CHAR[0]); break; } } function numeric_entity_4_char( $char ) { return "&#".str_pad(ord($char), 3, '0', STR_PAD_LEFT).";"; } } ---- Server IP: 208.69.120.55 Probable Submitter: 67.0.87.214 ---- Manual Page -- http://www.php.net/manual/en/function.htmlentities.php Edit -- https://master.php.net/note/edit/106535 Del: integrated -- https://master.php.net/note/delete/106535/integrated Del: useless -- https://master.php.net/note/delete/106535/useless Del: bad code -- https://master.php.net/note/delete/106535/bad+code Del: spam -- https://master.php.net/note/delete/106535/spam Del: non-english -- https://master.php.net/note/delete/106535/non-english Del: in docs -- https://master.php.net/note/delete/106535/in+docs Del: other reasons-- https://master.php.net/note/delete/106535 Reject -- https://master.php.net/note/reject/106535 Search -- https://master.php.net/manage/user-notes.php
