note 93533 added to function.ctype-space

A function I wrote last night was fairly flexible in terms of detecting whitespace, and even took into account the pesky non-breaking spaces / zero-width spaces further up the Unicode alphabet. The benefit here was being able to isolate and identify specific Unicode indices based on their subrange. // Returns TRUE if the ASCII value of $string matches a registered whitespace character. // * This includes non-breaking spaces, zero-width spaces, and any unicode values below 32. // * $string: Character to identify. If string extends past one character, the value // is truncated and only the initial character is examined. function is_whitespace($string){ // Return FALSE if passed an empty string. if($string == "") return FALSE; $char = ord($string); // Control Characters if($char < 33) return TRUE; if($char > 8191 && $char < 8208) return TRUE; if($char > 8231 && $char < 8240) return TRUE; // Additional Characters switch($char){ case 160: // Non-Breaking Space case 8287: // Medium Mathematical Space return TRUE; break; } return FALSE; } ---- Server IP: 69.147.83.197 Probable Submitter: 218.214.137.71 ---- Manual Page -- http://www.php.net/manual/en/function.ctype-space.php Edit -- https://master.php.net/note/edit/93533 Del: integrated -- https://master.php.net/note/delete/93533/integrated Del: useless -- https://master.php.net/note/delete/93533/useless Del: bad code -- https://master.php.net/note/delete/93533/bad+code Del: spam -- https://master.php.net/note/delete/93533/spam Del: non-english -- https://master.php.net/note/delete/93533/non-english Del: in docs -- https://master.php.net/note/delete/93533/in+docs Del: other reasons-- https://master.php.net/note/delete/93533 Reject -- https://master.php.net/note/reject/93533 Search -- https://master.php.net/manage/user-notes.php
