Jank Profiler

For when you don't want to figure out actual profilers.

Use Jank Profiler to wrap individual objects in your application to track memory usage and execution time of method calls belonging to that objects public api.

Usage

Let's say you have some code in your application that looks like this:

$myQuestionableObject = new WhompWhompDoDad(['thinger_option_x' => true]);
$whompTimes = 3;
$myQuestionableObject->whomp($whompTimes);
$myQuestionableObjecct->doDad();

you can jank profile the WhompWhompDoDad instance like this:

$myQuestionableObject = new JankProfiler('WhompWhompDoDad', [['thinger_option_x' => true]]);
$whompTimes = 3;
$myQuestionableObject->whomp($whompTimes);
$myQuestionableObjecct->doDad();

echo $myQuestionableObject->report('json') . "\n"; exit;

This will produce JSON output similar to:

[
    {
        "type": "construct",
        "meta": {
            "classname": "WhompWhompDoDad",
            "constructor_args": [
                {
                    "thinger_option_x":  true
                }
            ]
        },
        "memory_before": 464280,
        "start_time": 1425158122.1155,
        "memory_after": 477968,
        "end_time": 1425158122.116
    },
    {
        "type": "method call",
        "meta": {
            "method": "whomp",
            "arguments": [
                3
            ]
        },
        "start_time": 1425158122.116,
        "memory_before": 479896,
        "end_time": 1425158122.116,
        "memory_after": 480312
    },
    {
        "type": "method call",
        "meta": {
            "method": "doDad",
            "arguments": []
        },
        "start_time": 1425158122.116,
        "memory_before": 481976,
        "end_time": 1425158122.116,
        "memory_after": 482344
    }
]

Pretty neat!
