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 );

?>
