ldap_connect — Connect to an LDAP server
Description
$ldap_uri = NULL
] ) : resourceThe following signature is still supported for backwards compatibility, but is considered deprecated and should not be used anymore!
$host = NULL
[, int $port = 389
]] ) : resource
Creates an LDAP link identifier and checks whether the given
host and port are plausible.
Note: 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.
Parameters
-
ldap_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.
Return Values
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.
