本文实例讲述了PHP实现将颜色hex值转换成rgb的方法。分享给大家供大家参考，具体如下：
function hex2rgb( $colour ) {
if ( $colour == '#' ) {
$colour = substr( $colour, 1 );
}
if ( strlen( $colour ) == 6 ) {
list( $r, $g, $b ) = array( $colour . $colour, $colour . $colour, $colour . $colour );
} elseif ( strlen( $colour ) == 3 ) {
list( $r, $g, $b ) = array( $colour . $colour, $colour . $colour, $colour . $colour );
} else {
return false;
}
$r = hexdec( $r );
$g = hexdec( $g );
$b = hexdec( $b );
return array( 'red' => $r, 'green' => $g, 'blue' => $b );
}
//测试
var_dump(hex2rgb("#eeeeee"));
