ldap_connect — Connect to an LDAP server
说明
$ldap_uri = NULL ] ) :
resource
The 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.
参数
-
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.
返回值
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.
