ldap_errno

(PHP 4, PHP 5)

ldap_errnoReturn the LDAP error number of the last LDAP command

Description

int ldap_errno ( resource $link_identifier )

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

link_identifier

An LDAP link identifier, returned by ldap_connect().

Return Values

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

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";
?>

Couple of good error codes to get started.  If you want to detect failure of ldap_add due to the record already existing, ldap_error == 0x44.  This means, you can do something like:

$r = ldap_add($ds, $dn, $info);
if (!$r) {
    if (ldap_errno($ds) == 0x44) {
         // Do something about it
    } else {
         // A real failure
    }
}

Similarly, on ldap_delete, you will get a 0x20 value (No Such Object) if you try to delete something that isn't there.
