ldap_errno

(PHP 4, PHP 5, PHP 7, PHP 8)

ldap_errno — Return the LDAP error number of the last LDAP command

Description

ldap_errno(LDAP\Connection $ldap): int

Returns the standardized error number returned by the last LDAP command. This number can be converted into a textual error message using ldap_err2str().

Parameters

ldap: An LDAP\Connection instance, returned by ldap_connect().

Return Values

Return the LDAP error number of the last LDAP command for this link.

Changelog

Version	Description
8.1.0	The `ldap` parameter expects an LDAP\Connection instance now; previously, a valid `ldap link` resource was expected.

Examples

Unless you lower your warning level in your php.ini sufficiently or prefix your LDAP commands with @ (at) characters to suppress warning output, the errors generated will also show up in your HTML output.

Example #1 Generating and catching an error

<?php
// This example contains an error, which we will catch.
$ld = ldap_connect("localhost");
$bind = ldap_bind($ld);
// syntax error in filter expression (errno 87),
// must be "objectclass=*" to work.
$res =  @ldap_search($ld, "o=Myorg, c=DE", "objectclass");
if (!$res) {
    echo "LDAP-Errno: " . ldap_errno($ld) . "<br />\n";
    echo "LDAP-Error: " . ldap_error($ld) . "<br />\n";
    die("Argh!<br />\n");
}
$info = ldap_get_entries($ld, $res);
echo $info["count"] . " matching entries.<br />\n";
?>
