XHProf是一个针对PHP的函数级层次化分析器，具有基于HTML的简单导航界面。原始数据收集组件是用C语言（作为PHP扩展）实现的。报告/用户界面层全部用PHP编写。它能够报告每个函数的函数级包含和排除墙时、内存使用、CPU时间和调用次数。此外，它还支持比较两个运行（层次化DIFF报告）或聚合多个运行的结果。

本版本支持PHP7

php.ini配置

开启额外收集

PDO::exec

PDO::query

mysqli_query

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

输出数据

mysqli::query#SELECT * FROM user LIMIT 10

PDO::prepare

将预处理占位符转换为实际参数，更直观的分析性能（不改变zend执行过程）

$_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();

输出数据

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);

输出数据

curl_exec#http://www.baidu.com
