note 73255 added to function.dechex

The rgbhex function by AsakuraStar won't work for small values, eg (15,15,15) should return 0F0F0F, not FFF. I suggest the following: <?php function rgbhex($red, $green, $blue) { // force the passed value to be numeric by adding zero // use max and min to limit the number to between 0 and 255 // shift the number to make it the correct future hex value $red = 0x10000 * max(0,min(255,$red+0)); $green = 0x100 * max(0,min(255,$green+0)); $blue = max(0,min(255,$blue+0)); // convert the combined value to hex and zero-fill to 6 digits return "#".str_pad(strtoupper(dechex($red + $green + $blue)),6,"0",STR_PAD_LEFT); } ?> Maybe in future dechex will have a size parameter, as in: dechex($red+$green+$blue , 6) This would especially be useful for negative numbers. dechex(-1 , 2) would then give ff. ---- Server IP: 216.235.15.211 Probable Submitter: 142.204.211.186 ---- Manual Page -- http://www.php.net/manual/en/function.dechex.php Edit -- https://master.php.net/note/edit/73255 Del: integrated -- https://master.php.net/note/delete/73255/integrated Del: useless -- https://master.php.net/note/delete/73255/useless Del: bad code -- https://master.php.net/note/delete/73255/bad+code Del: spam -- https://master.php.net/note/delete/73255/spam Del: non-english -- https://master.php.net/note/delete/73255/non-english Del: in docs -- https://master.php.net/note/delete/73255/in+docs Del: other reasons-- https://master.php.net/note/delete/73255 Reject -- https://master.php.net/note/reject/73255 Search -- https://master.php.net/manage/user-notes.php
