quick regular expression help

[mcshen]

i read so many tutorials. but, i am too stupid to learn how to do this.
just need a regular expression for something like

&link=cdrom
&link=xbox
&link=ps2
&link=pc

i tried
(preg_match("/$link=*/i",$line)

this didn't work.

(preg_match("/$link=./i",$line)

does work either

(preg_match("/$link=*/i",$line)

well if you are trying to match $link against &link .... You'll be ther for a long time.

$line = "hello how are you doing";
if(!preg_match("/how/", $line))
{
echo "nope";
}

whatever is between the / and the / has to match perfectly otherwise will return false.

There are quite a few characters that may have to be escaped in a preg_match. I think $ is one of them.

Looks to me like you are looking for something like this:

<?PHP
$link = "&link=foo";

if (preg_match("/^&link=.*/i",$link)) {
	echo "A match was found.";
}
else {
	echo "A match was not found.";
}

?>
