MongoCommandCursor::info — Gets the query, fields, limit, and skip for this cursor
This can be called before or after the query.
Questa funzione non contiene parametri.
Returns the namespace, limit, skip, query, fields, connection and iteration information for this cursor.
Example #1 MongoCommandCursor::info() example
<?php
$m = new MongoClient();
$c = $m->test->test;
$cursor = $c->commandCursor( [
'aggregate' => 'test',
'pipeline' => [
[ '$match' => [ '_id' => [ '$exists' => true ] ] ],
]
] );
echo "Before iteration started:\n";
var_dump($cursor->info());
echo "Aftere iteration started:\n";
$cursor->rewind();
var_dump($cursor->info());
?>
Il precedente esempio visualizzerà qualcosa simile a:
Before iteration started:
array(8) {
'ns' =>
string(9) "test.test"
'limit' =>
int(0)
'batchSize' =>
int(0)
'skip' =>
int(0)
'flags' =>
int(0)
'query' =>
array(2) {
'aggregate' =>
string(4) "test"
'pipeline' =>
array(1) {
[0] =>
array(1) {
'$match' =>
array(1) {
'_id' =>
array(1) {
'$exists' =>
bool(true)
}
}
}
}
}
'fields' =>
NULL
'started_iterating' =>
bool(false)
}
Aftere iteration started:
array(17) {
'ns' =>
string(9) "test.test"
'limit' =>
int(0)
'batchSize' =>
int(101)
'skip' =>
int(0)
'flags' =>
int(0)
'query' =>
array(3) {
'aggregate' =>
string(4) "test"
'pipeline' =>
array(1) {
[0] =>
array(1) {
'$match' =>
array(1) {
'_id' =>
array(1) {
'$exists' =>
bool(true)
}
}
}
}
'cursor' =>
array(1) {
'batchSize' =>
int(101)
}
}
'fields' =>
NULL
'started_iterating' =>
bool(true)
'id' =>
int(0)
'at' =>
int(0)
'numReturned' =>
int(0)
'server' =>
string(24) "localhost:27017;-;.;2316"
'host' =>
string(9) "localhost"
'port' =>
int(27017)
'connection_type_desc' =>
string(10) "STANDALONE"
'firstBatchAt' =>
int(0)
'firstBatchNumReturned' =>
int(1)
}
