ldap_connect

Name

ldap_connect — Connects to an LDAP server prior to performing operations.

Synopsis

resource ldap_connect([host][, port][, wallet]); string host (optional): LDAP server int port (optional): Server port string wallet (optional): SSL-enabled LDAP walletSSL-enabled wallet passwordSSL-enabled LDAP authorization mode

Returns

LDAP connection ID; FALSE on error

Description

Opens a connection to an LDAP server and returns the connection ID. By default, a connection is made to port 389 if the port is not specified. If the hostname is not specified, the current connection ID is returned. Multiple connections can be built as an array to be used with the searching functions, and may be used in place of a single host string entry. The SSL options are available only when using an SSL LDAP library such as the Oracle library.

Note

Not all functions honor the convention of using an array, so more direct manipulations require using a single host. Arrays are best used for general searches.

Note

The SSL options are available only when using an SSL LDAP library.

Version

PHP Version: 3+, 4+

Example

Example 628. Open a single LDAP connection

$host = "ldap.foo.com";
if (!$ldapconn = ldap_connect($host, 389)) {
   echo "Error! Could not connect to LDAP host $host\n";
}

Example 629. Open multiple LDAP connections

$host1 = "ldap.foo.com";
$host2 = "ldap1.foo.com";
$host3 = "ldap2.foo.com";
$connarray[] = $ldapconn1 = ldap_connect($host1, 389);
$connarray[] = $ldapconn2 = ldap_connect($host2, 389);
$connarray[] = $ldapconn3 = ldap_connect($host3, 389);
