PHP Help? Gurus, hook a brother up...

Been a while since I wrote code and I'm working on a small script and sadly I'm stuck on what should be a relatively easy regular expression match in PHP.

I have a variable with a bunch of text and need to match the text between two different patterns and assign it to a variable.

Ex.
$a="...$agentid=1010303&listingid...etc.";

I need to grab text between $agentid= and &listingid and assign to variable so I am left with $num="1010303". Now, I have to do some things with that number but first need to extract it from the variable.

Rather than sift through web pages and using trial and error, I figure one of you guys can spew it out off the top of your head.

Any ideas?

PHP Code:


		
			
$str = '$agentid=1010303&listingid';

if(preg_match_all('/agentid\=(\d+)&listingid/',$str,$matches)){

    $num = $matches[1][0];

}

Really? Let me add another. drocd should remember this regex I pasted him a while ago.

PHP Code:


		
			
@ox.+ref = "(.+)".+c="(.+)".+e="(.+)".+ft">(.+)<@Us

Rails is for snails.

Here, have a link scraper.

Code:

$preg = "/a[\s]+[^>]*?href[\s]?=[\s\"\']+(.*?)[\"\']+.*?>([^<]+|.*?)?<\/a>/i";

Whats wrong with
$num = $a['agentid']

As Bird suggested, if those variables are actually part of the URL that is running the script then it's easy peasy... $num = $_GET["agentid"]; (replace GET with POST if it's a form)

Why does everybody hate $_REQUEST?

I was praying that's what Bird meant, and not eval() parse_str($_SERVER["QUERY_STRING"]). You can only imagine what kind of shit I've seen to even assume such a crazy thing

Just habit from writing scripts that are to be used by several people. Keep it more specific.

Some webmasters will do odd things, like a javascript call that redirects to your site by POSTing to it. (The reason for this? It blocks/clears the referer.)

although, cos I know what you're doing :winkwink: the agent id is a 10 digit string and will only occur once, so to be absolutely sure....

if(preg_match('/agentid\=(\d{10})&listingid/',$str,$matches)){

cos otherwise, the regexp given would pick up also:

$a="...$agentid=1&listingid...etc.";

:2 cents: <- my invoice for this wonderful piece of insight

You've done two things wrong for the adult industry:

1) Assuming he has the variable defined locally.
2) Assuming he knows what a variable is.
