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.

This version supports PHP7 and PHP8

xhprof_enable(XHPROF_FLAGS_NO_BUILTINS | XHPROF_FLAGS_CPU | XHPROF_FLAGS_MEMORY);

• XHPROF_FLAGS_NO_BUILTINS do not profile builtins
• XHPROF_FLAGS_CPU gather CPU times for funcs
• XHPROF_FLAGS_MEMORY gather memory usage for funcs

Example

<?php

array(
    "main()" => array(
        "wt" => 237,
        "ct" => 1,
        "cpu" => 100,
    )
)

• wt The execution time of the function method is time consuming
• ct The number of times the function was called
• cpu The CPU time consumed by the function method execution
• mu Memory used by function methods. The call is zend_memory_usage to get the memory usage
• pmu Peak memory used by the function method. The call is zend_memory_peak_usage to get the memory

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

mysqli::query#SELECT * FROM user LIMIT 10

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();

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