Example 1117. 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.
