示例 #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);

User Contributed Notes 1 note
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);
