范例

Example #1 MongoCursor::info() example


<?php

$m = new MongoClient();
$cursor = $m->foo->bar->find(array("x" => 4), array("y" => false));
var_dump($cursor->info());

?>

以上例程的输出类似于：

array(5) {
  ["ns"]=>
  string(7) "foo.bar"
  ["limit"]=>
  int(0)
  ["skip"]=>
  int(0)
  ["query"]=>
  array(1) {
    ["x"]=>
    int(4)
  }
  ["fields"]=>
  array(1) {
    ["y"]=>
    int(0)
  }
}
