ldap_connectConnect to an LDAP server


ldap_connect ([ string $ldap_uri = NULL ] ) : resource

The following signature is still supported for backwards compatibility, but is considered deprecated and should not be used anymore!

ldap_connect ([ string $host = NULL [, int $port = 389 ]] ) : resource

Creates an LDAP link identifier and checks whether the given host and port are plausible.

Bilginize: This function does not open a connection. It checks whether the given parameters are plausible and can be used to open a connection as soon as one is needed.



A full LDAP URI of the form ldap://hostname:port or ldaps://hostname:port for SSL encryption.

You can also provide multiple LDAP-URIs separated by a space as one string

Note that hostname:port is not a supported LDAP URI as the schema is missing.


The hostname to connect to.


The port to connect to.

Dönen Değerler

Returns a positive LDAP link identifier when the provided LDAP URI seems plausible. It's a syntactic check of the provided parameter but the server(s) will not be contacted! If the syntactic check fails it returns FALSE. ldap_connect() will otherwise 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 argument is specified then the link identifier of the already opened link will be returned.
