MongoCommandCursor::info — Gets information about the cursor's creation and iteration
Beschreibung
public MongoCommandCursor::info
( void
) : array
This can be called before or after the cursor has started iterating.
Parameter-Liste
Diese Funktion besitzt keine Parameter.
Rückgabewerte
Returns the namespace, batch size, limit, skip, flags, query, and projected fields for this cursor. If the cursor has started iterating, additional information about iteration and the connection will be included.
Beispiele
Beispiel #1 MongoCommandCursor::info() example
<?php
$m = new MongoClient();
$cursor = new MongoCommandCursor(
$m, // MongoClient object
'demo.cities', // namespace
[
'aggregate' => 'cities',
'pipeline' => [ [ '$match' => [ '_id' => [ '$exists' => true ] ] ] ],
'cursor' => [ 'batchSize' => 1 ],
]
);
echo "Before iteration started:\n";
var_dump($cursor->info());
echo "\nAfter iteration started:\n";
$cursor->rewind();
var_dump($cursor->info());
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Before iteration started:
array(8) {
["ns"]=>
string(11) "demo.cities"
["limit"]=>
int(0)
["batchSize"]=>
int(0)
["skip"]=>
int(0)
["flags"]=>
int(0)
["query"]=>
array(3) {
["aggregate"]=>
string(6) "cities"
["pipeline"]=>
array(1) {
[0]=>
array(1) {
["$match"]=>
array(1) {
["_id"]=>
array(1) {
["$exists"]=>
bool(true)
}
}
}
}
["cursor"]=>
array(1) {
["batchSize"]=>
int(1)
}
}
["fields"]=>
NULL
["started_iterating"]=>
bool(false)
}
After iteration started:
array(17) {
["ns"]=>
string(11) "demo.cities"
["limit"]=>
int(0)
["batchSize"]=>
int(0)
["skip"]=>
int(0)
["flags"]=>
int(0)
["query"]=>
array(3) {
["aggregate"]=>
string(6) "cities"
["pipeline"]=>
array(1) {
[0]=>
array(1) {
["$match"]=>
array(1) {
["_id"]=>
array(1) {
["$exists"]=>
bool(true)
}
}
}
}
["cursor"]=>
array(1) {
["batchSize"]=>
int(1)
}
}
["fields"]=>
NULL
["started_iterating"]=>
bool(true)
["id"]=>
int(185840310129)
["at"]=>
int(0)
["numReturned"]=>
int(0)
["server"]=>
string(25) "localhost:27017;-;.;23991"
["host"]=>
string(9) "localhost"
["port"]=>
int(27017)
["connection_type_desc"]=>
string(10) "STANDALONE"
["firstBatchAt"]=>
int(0)
["firstBatchNumReturned"]=>
int(1)
}
