复制代码代码如下:
<?php
function hex2rgb($colour) {
    if ($colour [0] == '#') {
        $colour = substr ( $colour, 1 );
    }
    if (strlen ( $colour ) == 6) {
        list ( $r, $g, $b ) = array ($colour [0] . $colour [1], $colour [2] . $colour [3], $colour [4] . $colour [5] );
    } elseif (strlen ( $colour ) == 3) {
        list ( $r, $g, $b ) = array ($colour [0] . $colour [0], $colour [1] . $colour [1], $colour [2] . $colour [2] );
    } else {
        return false;
    }
    $r = hexdec ( $r );
    $g = hexdec ( $g );
    $b = hexdec ( $b );
    return array ('red' => $r, 'green' => $g, 'blue' => $b );
}
$b = hex2rgb ( "#ff0" );
print_r ( $b );
?>
