ldap_connect — Connect to an LDAP server
As of PHP 8.3.0, the following signature is deprecated.
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.
hostThe 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.
