Example #1 MongoCollection::find() example
This example demonstrates how to search for a range.
<?php
$m = new Mongo;
$c = $m->selectCollection('project', 'outfits');
var_dump($c->getIndexInfo());
?>
The above example will output:
array(8) {
[0] =>
array(3) {
'name' =>
string(4) '_id_'
'ns' =>
string(12) 'project.outfits'
'key' =>
array(1) {
'_id' =>
int(1)
}
}
...
[7] =>
array(4) {
'_id' =>
class MongoId#12 (1) {
public $$id => string(24) '4d6f7abd44670a1513190000'
}
'ns' =>
string(12) 'project.outfits'
'key' =>
array(2) {
'created' =>
int(-1)
'userid' =>
int(1)
}
'name' =>
string(19) 'created_-1_userid_1'
}
}
