一个很使用的php颜色转换函数,用于将hex表示的颜色值转换为rgb格式。例如:#dfdfdf转换成(239,239,239)
<?php <br /> function hex2rgb( $colour ) {<br> if ( $colour[0] == '#' ) {<br> $colour = substr( $colour, 1 );<br> }<br> if ( strlen( $colour ) == 6 ) {<br> list( $r, $g, $b ) = array( $colour[0] . $colour[1], $colour[2] . $colour[3], $colour[4] . $colour[5] );<br> } elseif ( strlen( $colour ) == 3 ) {<br> list( $r, $g, $b ) = array( $colour[0] . $colour[0], $colour[1] . $colour[1], $colour[2] . $colour[2] );<br> } else {<br> return false;<br> }<br> $r = hexdec( $r );<br> $g = hexdec( $g );<br> $b = hexdec( $b );<br> return array( 'red' => $r, 'green' => $g, 'blue' => $b );<br> }<br> ?>http://blog.ddian.cn/?post=896
