获取字符串中的颜色代码

Question

I have a string like

<font color="#ffffff">Heippa </font><b><i><u><font face="Calibri" color="#e71818">rallaa</font></u></i></b>

And I need to get all color codes seperated in a array

['#ffffff','#e71818']

Is there a easy way to do this. I know you can use strrchr to find all # marks and substr($color, 0, 7), but that will print out only the last found mark.

Thank you for your advice.

 $input='<font color="#ffffff">Heippa </font><b><i><u><font face="Calibri" color="#e71818">rallaa</font></u></i></b>';   
 preg_match_all("/#[0-9a-f]{6}/i", $input, $output);
 print_r($output);
