michaellunsford Posted January 19, 2007 Share Posted January 19, 2007 I'm wanting to convert a web color, like FF0000 to an RGB value, 255,0,0. I was going to substr the web color and make my own math function. Before I do all that, is there a built-in function that does this already? Or something close?Thanks!

redbullmarky Posted January 19, 2007 Share Posted January 19, 2007 [url=http://uk2.php.net/hex2dec]hex2dec[/url] should set you on your way ;)you'll just have to note that each pair in the 6 character hex string amounts to a number, so you will (as far as i know, unless there's another specific function) have to split it up first into 3 parts and then perform the hex2dec conversions. the user notes on the php manual hex2dec page does bring up the subject of converting colours though.cheers Link to comment https://forums.phpfreaks.com/topic/34931-php-function-to-convert-ff-to-255/#findComment-164712 Share on other sites More sharing options...
