xhprof for PHP7

XHProf is a function-level hierarchical profiler for PHP and has a simple HTML based navigational interface. The raw data collection component is implemented in C (as a PHP extension). The reporting/UI layer is all in PHP. It is capable of reporting function-level inclusive and exclusive wall times, memory usage, CPU times and number of calls for each function. Additionally, it supports ability to compare two runs (hierarchical DIFF reports), or aggregate results from multiple runs.

Turn on extra collection

PDO::exec

PDO::query

mysqli_query

$mysqli = new mysqli("localhost", "my_user", "my_password", "user");
$result = $mysqli->query("SELECT * FROM user LIMIT 10");

Output data

mysqli::query#SELECT * FROM user LIMIT 10

PDO::prepare

Convert preprocessing placeholders for actual parameters, more intuitive analytic performance (does not change the zend execution process)

$_sth = $db->prepare("SELECT * FROM user where userid = :id and username = :name");
$_sth->execute([':id' => '1', ':name' => 'admin']);
$data1 = $_sth->fetch();

$_sth = $db->prepare("SELECT * FROM user where userid = ?");
$_sth->execute([1]);
$data2 = $_sth->fetch();

Output data

PDOStatement::execute#SELECT * FROM user where userid = 1 and username = admin
PDOStatement::execute#SELECT * FROM user where userid = 1

Curl

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.baidu.com");
$output = curl_exec($ch);
curl_close($ch);

Output data

curl_exec#http://www.baidu.com
