Przykłady

Przykład #1 MongoCursor::info() example

<?php
$m 
= new MongoClient();

$cursor $m->test->foo->find(array("x" => 4), array("y" => 0));

echo 
"Before iteration started:\n";
var_dump($cursor->info());

echo 
"\nAfter iteration started:\n";
$cursor->rewind();
var_dump($cursor->info());

?>

Powyższy przykład wyświetli coś podobnego do:

Before iteration started:
array(8) {
  ["ns"]=>
  string(8) "test.foo"
  ["limit"]=>
  int(0)
  ["batchSize"]=>
  int(0)
  ["skip"]=>
  int(0)
  ["flags"]=>
  int(0)
  ["query"]=>
  array(1) {
    ["x"]=>
    int(4)
  }
  ["fields"]=>
  array(1) {
    ["y"]=>
    int(0)
  }
  ["started_iterating"]=>
  bool(false)
}

After iteration started:
array(15) {
  ["ns"]=>
  string(8) "test.foo"
  ["limit"]=>
  int(0)
  ["batchSize"]=>
  int(0)
  ["skip"]=>
  int(0)
  ["flags"]=>
  int(0)
  ["query"]=>
  array(1) {
    ["x"]=>
    int(4)
  }
  ["fields"]=>
  array(1) {
    ["y"]=>
    int(0)
  }
  ["started_iterating"]=>
  bool(true)
  ["id"]=>
  int(0)
  ["at"]=>
  int(0)
  ["numReturned"]=>
  int(1)
  ["server"]=>
  string(25) "localhost:27017;-;.;26450"
  ["host"]=>
  string(9) "localhost"
  ["port"]=>
  int(27017)
  ["connection_type_desc"]=>
