ldap_connect
Connect to an LDAP server
(PHP 4, PHP 5)
resource ldap_connect ( [string hostname [, int port]] )
Parameters
- hostname
If you are using OpenLDAP 2.x.x you can specify a URL instead of the hostname. To use LDAP with SSL, compile OpenLDAP 2.x.x with SSL support, configure PHP with SSL, and set this parameter as
ldaps://hostname/.- port
The port to connect to. Not used when using URLs. Defaults to 389.
Return Values
Returns a positive LDAP link identifier on success, or FALSE on error.
When OpenLDAP 2.x.x is used, ldap_connect() will always
return a resource as it does not actually connect but just
initializes the connecting parameters. The actual connect happens with
the next calls to ldap_* funcs, usually with
ldap_bind().
If no arguments are specified then the link identifier of the already opened link will be returned.
Examples
Example 1114. Example of connecting to LDAP server.
<?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");
?>
Example 1115. Example of connecting securely to LDAP server.
<?php
// make sure your host is the correct one
// that you issued your secure certificate to
$ldaphost = "ldaps://ldap.example.com/";
// Connecting to LDAP
$ldapconn = ldap_connect($ldaphost)
or die("Could not connect to {$ldaphost}");
