PHP method to convert color hex value into rgb

The example in this article describes the method of converting color hex value into rgb in PHP. Share it with everyone for your reference, the details are as follows:

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 ); 
} 
//测试 
var_dump(hex2rgb("#eeeeee"));

The running results are as follows:

array(3) {
 ["red"]=>
 int(238)
 ["green"]=>
 int(238)
 ["blue"]=>
 int(238)
}
