PHP - Catch timeout exception from ldap_connect()

php timeout ldap ldapconnection
TehQuila picture TehQuila · Dec 7, 2011 · Viewed 8.1k times · Source

I've written a little monitoring script in PHP, which should monitor a virtual directory and it's active directories. Everything works fine but when the virtual directory service freezes is my ldap_connect() not able to connect but also doesn't get an error back. So my whole script stands still. I think that the ldap_connect function gets a timeout back (like when you try to ping an IP and it's not reachable).

That's my connect command:

$connection = ldap_connect($hostname, $port) or die("Could not connect to {$hostname});

And I haven't found something in the manual for ldap_connect() (manual) about a timelimit parameter in which you could define how long the function should try to connect until it aborts.

How ever I wasn't quite able to come up with a solution with try and catch or something like this. I also didn't wanted to use the set_time_limit() function because my script needs to be run until the end.

I appreciate every help :) Thanks and greetings Tim
