This example reports the execution time for a map-reduce operation.
.. code-block:: php
<?php
$collection = (new MongoDB\Client)->test->zips;
$map = new MongoDB\BSON\Javascript('function() { emit(this.state, this.pop); }');
$reduce = new MongoDB\BSON\Javascript('function(key, values) { return Array.sum(values) }');
$out = ['inline' => 1];
$result = $collection->mapReduce($map, $reduce, $out);
var_dump($result->getExecutionTimeMS());
The output would then resemble::
int(244)
