ldap_connect — Connect to an LDAP server
The following signature is still supported for backwards compatibility (except for using named parameters), but is considered deprecated and should not be used anymore!
Creates an LDAP\Connection connection and checks whether the given
uri is plausible.
注意: 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.
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.
uriThe hostname to connect to.
portThe port to connect to.
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.
| 版本 | 说明 |
|---|---|
| 8.1.0 | Returns an LDAP\Connection instance now; previously, a 资源(resource) was returned. |
