EXAMPLES
Example #1
MongoCursor.info(3) example
<?php
$m = new MongoClient();
$cursor = $m->test->foo->find(array("x" => 4), array("y" => 0));
echo "Before iteration started:
";
var_dump($cursor->info());
echo "
After iteration started:
";
$cursor->rewind();
var_dump($cursor->info());
?>
The above example will output something similar to:
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"]=>
string(10) "STANDALONE"
}
