linkAn LDAP link identifier, returned by ldap_connect().
reqoid
The extended operation request OID. You may use one of LDAP_EXOP_START_TLS, LDAP_EXOP_MODIFY_PASSWD, LDAP_EXOP_REFRESH, LDAP_EXOP_WHO_AM_I, LDAP_EXOP_TURN, or a string with the OID of the operation you want to send.
reqdata
The extended operation request data. May be NULL for some operations like LDAP_EXOP_WHO_AM_I, may also need to be BER encoded.
serverctrlsArray of LDAP Controls to send with the request.
retdataWill be filled with the extended operation response data if provided. If not provided you may use ldap_parse_exop on the result object later to get this data.
retoidWill be filled with the response OID if provided, usually equal to the request OID.

When used without retdata, returns a result identifier or FALSE on error.

Example #1 Whoami extended operation
<?php
$ds = ldap_connect("localhost"); // assuming the LDAP server is on this host
if ($ds) {
// bind with appropriate dn to give update access
$bind = ldap_bind($ds, "cn=root, o=My Company, c=US", "secret");
if (!$bind) {
echo "Unable to bind to LDAP server";
exit;
}
// Call WHOAMI EXOP
$r = ldap_exop($ds, LDAP_EXOP_WHO_AM_I);
// Parse the result object
ldap_parse_exop($ds, $r, $retdata);
// Output: string(31) "dn:cn=root, o=My Company, c=US"
var_dump($retdata);
// Same thing using $retdata parameter
$success = ldap_exop($ds, LDAP_EXOP_WHO_AM_I, NULL, NULL, $retdata, $retoid);
if ($success) {
var_dump($retdata);
}
ldap_close($ds);
} else {
echo "Unable to connect to LDAP server";
}
?>
The following can be used to run the refresh command in PHP 7.2 as ldap_exop_refresh comes with 7.3.
$dn= 'cn=user,dc=test,dc=org';
$ttl = 3600;
$data = '';
$data .= '80' . sprintf("%'.02x", strlen($dn)) . bin2hex($dn);
$data .= '81' . sprintf("%'.02x", 4) . sprintf("%'.08x", $ttl);
$data = hex2bin('30' . sprintf("%'.02x", strlen($data)/2) . $data);
$success = ldap_exop($ldapHandle, LDAP_EXOP_REFRESH, $data);
