Matching data in MongoDB using PHP involves using the "find" method and passing a query as a parameter. The query is constructed using the keys and values of the fields that need to be matched. Here's an example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
// Connect to MongoDB
$mongo = new MongoDBClient;
// Select the database and collection
$db = $mongo->selectDatabase('mydb');
$collection = $db->selectCollection('mycollection');
// Construct the query
$query = array('name' => 'John', 'age' => 30);
// Find the matching documents
$cursor = $collection->find($query);
// Iterate over the results
foreach ($cursor as $doc) {
echo $doc->_id . ': ' . $doc->name . ' (' . $doc->age . ')' . '<br>';
}

In this example, we're matching documents with a "name" field equal to 'John' and an "age" field equal to 30. The "find" method returns a cursor object that can be iterated over to access the matched documents.
