    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.

    Örnek 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.
