HTML (test.htm)

<body>
<a href="test.php?mymac=XX:XX:XX:XX:XX:XX">Click to WOL XX:XX:XX:XX:XX:XX</a>
</body>

PHP (test.php)

<?php
$mymac = $_REQUEST['mymac'];
wol("255.255.255.255", $mymac);
echo 'WOL sent to '.$mymac;

function wol($broadcast, $mac){
$mac_array = preg_split('#:#', $mac); //print_r($mac_array);
$hwaddr = '';
    foreach($mac_array AS $octet){
    $hwaddr .= chr(hexdec($octet));
    }
    //Magic Packet
    $packet = '';
    for ($i = 1; $i <= 6; $i++){
    $packet .= chr(255);
    }
    for ($i = 1; $i <= 16; $i++){
    $packet .= $hwaddr;
    }
    //set up socket
    $sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
    if ($sock){
    $options = socket_set_option($sock, 1, 6, true);
        if ($options >=0){    
        $e = socket_sendto($sock, $packet, strlen($packet), 0, $broadcast, 7);
        socket_close($sock);
        }    
    }
}  //end function wol
?>

Since the split() function was removed from PHP 7.0.0, this script uses preg_split() to be compatible with current and previous PHP versions.

Replace XX:XX:XX:XX:XX:XX in the HTML with your target MAC to test the script.

I know this is an old questions, but it's still the first Google result, so here's what I ended up doing after a bit of research:

Prerequisites:
- Linux box on the same network
- Install the wakeonlan package from your system's package manager
  (i.e. sudo apt-get install wakeonlan)
Now the script is as easy as this:
```
<?php
    # replace with your target MAC address
    $mac = 'aa:bb:cc:11:22:33';

    exec("wakeonlan $mac");
?>
```
Hope that helps someone.

function wol($broadcast, $mac)
{
    $hwaddr = pack('H*', preg_replace('/[^0-9a-fA-F]/', '', $mac));

    // Create Magic Packet
    $packet = sprintf(
        '%s%s',
        str_repeat(chr(255), 6),
        str_repeat($hwaddr, 16)
    );

    $sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);

    if ($sock !== false) {
        $options = socket_set_option($sock, SOL_SOCKET, SO_BROADCAST, true);

        if ($options !== false) {
            socket_sendto($sock, $packet, strlen($packet), 0, $broadcast, 7);
            socket_close($sock);
        }
    }
}

Should work - call it with a broadcast IP address, and a MAC address

Building upon the previous answers. Had to set udp port to 9 and repeat the MAC a couple more times before it worked for me:

function wol($mac)
{
    $hwaddr = pack('H*', preg_replace('/[^0-9a-fA-F]/', '', $mac));

    // Create Magic Packet
    $packet = sprintf(
        '%s%s',
        str_repeat(chr(255), 6),
        str_repeat($hwaddr, 20)
    );

    $sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);

    if ($sock !== false) {
        $options = socket_set_option($sock, SOL_SOCKET, SO_BROADCAST, true);

        if ($options !== false) {
            socket_sendto($sock, $packet, strlen($packet), 0, "255.255.255.255", 9);
            socket_close($sock);
        }
    }
}
