There is no return value from ldap_connect() php

Question

Hello,

Currently, I'm working on PHP web application on wamp environment.

I'm quite new with ldap and right now, I have a pretty simple problem about it.

After I enabled LDAP support in PHP. I have tried to call ldap function with the following code:

<?php

// LDAP variables
$ldaphost = "ldap.example.com";  // your ldap servers
$ldapport = 389;                 // your ldap server's port number

// Connecting to LDAP
$ldapconn = ldap_connect($ldaphost, $ldapport)
          or die("Could not connect to $ldaphost");

echo $ldapconn;

?>

The problem is when I run this file, I've got no result. I can't see whether it's failed or not and after function "ldap_connect", whatever I tried to put it there. It doesn't work, even simple command e.g. echo "hello world";

What should I do?

Please Suggest.

ldap_connect returns resource. When trying to echo or doing var_dump($ldapconn); you should see something like resource #1 - it means your connection is ready to use. If your connection failed, die() will work for sure and probably PHP warning will be thrown.
