strip file

wanaka

function strip_files()
{
$file = "content.inc";
$fd = fopen($file, "r");
$contents = fread ($fd, filesize($file));
fclose($fd);
$contents = preg_replace ("graph.gif", "mygraph.gif", $contents);
$fp = fopen (strtolower($file), "a+");
fwrite ($fp, $contents);
fclose ($fp);

}

I want to change the image link. Just wondering how could I specify in the preg_replace syntax to look for graph.gif file and replace it with mygraph.gif

u can also do something like this:

$gr = "graph.gif";
$my_gr =  "mygraph.gif";

$change_gif = array($gr => $my_gr);
$contents = strtr($contents, $change_gif);

A few more steps but i think it'd work as well..!!

I have done the following it looks fine but it can only change the first one

function change_files()
{
$file = "content.inc";
$fd = fopen($file, "r");
$contents = fread ($fd, filesize($file));
fclose($fd);
$contents = preg_replace ("/graph*.gif/", "mygraph.gif", $contents);
$fp = fopen (strtolower($file), "a+");
fwrite ($fp, $contents);
fclose ($fp);

}

before change
