Stop part of the script

[KingOfHeart]

I'm not even sure what scripting language I need to use.

 

I'm using php to retrieve some chat data. This works fine, but every now and then it takes forever to load, which causes my main page to take forever.

 

Is there a way to stop reading data off of the site if it takes too long?

I tried some time out methods, but no luck so far.

how advanced are you in php?

 

If you're more advanced, you could try a socket, and after x amount of loops if you receive 0 bytes of data, then you could break; the loop..

 

or uhm..

 

set_time_limit

 

but that is for the ENTIRE php script's processing.. not just for 1 specific thing..

 

or just use file fuctions, and do the same thing as the socket would.. but that would probably give you the same problem as file_get_contents considering fopen and file_get_contents go thru the same initial processes

 

anyway goodluck

You could post your script, some people can help improve it speed or see if something is wrong.

The script is fine, trust me.

Everything above the line "//ignore everything above"

is just a special script for telling us admins if we got an inbox message.

 

Ok, I'm using file_get_contents to get the data. Can I tell it to only do this for so long?

I don't think you can do that with file get content but you can with cUrl

 

<?php
$timeout = 10;
$ch = curl_init("http://www.somesite.com/somepage.php");
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; en) Opera 9.64');
$output = curl_exec($ch);
curl_close($ch);

echo $output;
?>

 

The $timeout is in seconds.

sweet, didn't know that (didn't test it either)

[KingOfHeart]

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; en) Opera 9.64');

 

^ what's that for?

[Philip]

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; en) Opera 9.64');

That tells the other server what the browser it is - which is easily faked as seen above, mostly used for just statistics or for showing different content for different browsers

[gffg4574fghsDSGDGKJYM]

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; en) Opera 9.64');

I've got error from some website that block the curl default useragent. Now i always include a fake one, just in case.
