       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 />
";
		  echo "LDAP-Error: " . ldap_error($ld) . "<br />
";
		  die("Argh!<br />
");
	      }
	      $info = ldap_get_entries($ld, $res);
