Connect to an LDAP server ldap_compare ldap_count_entries LDAP Functions PHP Manual ldap_connect (PHP 4, PHP 5)ldap_connect — Connect to an LDAP server Description resource ldap_connect ([ string $hostname [, int $port ]] ) Establishes a connection to a LDAP server on a specified hostname and 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. ChangeLog Version Description 4.0.4 URL and SSL support was added.
