ldap_connect

(PHP 4, PHP 5, PHP 7, PHP 8)

ldap_connect — Connect to an LDAP server

Descrizione

ldap_connect(?string $uri = null): LDAP\Connection|false
Avviso

As of PHP 8.3.0, the following signature is deprecated.

ldap_connect(?string $host = null, int $port = 389): LDAP\Connection|false

Creates an LDAP\Connection connection and checks whether the given uri is plausible.

Nota: 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.

Elenco dei parametri

uri

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.

host

The hostname to connect to.

port

The port to connect to.

Valori restituiti

Returns an LDAP\Connection instance 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 LDAP\Connection instance as it does not actually connect but just initializes the connecting parameters. The actual connect happens with the next calls to ldap_* functions, usually with ldap_bind().

If no argument is specified then the LDAP\Connection instance of the already opened connection will be returned.
