note 83338 added to function.imagecolorallocate

Little correction to marc-gutt's regural expression to validate hex color values. You can use this little function: <?php // Validate an hex color string. Return true if valid, false otherwise function validateHexColor($color) { $color = substr($color, 0, 7); return preg_match('/#[0-9a-fA-F]{6}/', $color); } ?> ---- Server IP: 201.216.232.3 Probable Submitter: 200.126.254.144 ---- Manual Page -- http://www.php.net/manual/en/function.imagecolorallocate.php Edit -- https://master.php.net/note/edit/83338 Del: integrated -- https://master.php.net/note/delete/83338/integrated Del: useless -- https://master.php.net/note/delete/83338/useless Del: bad code -- https://master.php.net/note/delete/83338/bad+code Del: spam -- https://master.php.net/note/delete/83338/spam Del: non-english -- https://master.php.net/note/delete/83338/non-english Del: in docs -- https://master.php.net/note/delete/83338/in+docs Del: other reasons-- https://master.php.net/note/delete/83338 Reject -- https://master.php.net/note/reject/83338 Search -- https://master.php.net/manage/user-notes.php
