note 58219 added to function.dechex

A handy little function to convert HEX colour codes to "web safe" colours... <?php function color_mkwebsafe ( $in ) { // put values into an easy-to-use array $vals['r'] = hexdec( substr($in, 0, 2) ); $vals['g'] = hexdec( substr($in, 2, 2) ); $vals['b'] = hexdec( substr($in, 4, 2) ); // loop through foreach( $vals as $val ) { // convert value $val = ( round($val/51) * 51 ); // convert to HEX $out .= str_pad(dechex($val), 2, '0', STR_PAD_LEFT); } return $out; } ?> Example: color_mkwebsafe('0e5c94'); Produces: 006699 Hope this helps someone out...
