获取css源(url)的加载时间 - Getting loading time of css source (url)

Getting loading time of css source (url)

本文关键字：加载时间 url css 获取 | 更新日期: 2023-09-27

我想获得加载时间在毫秒，一个url。它可能是css, js或img url。例如- http://images.apple.com/global/nav/styles/navigation.css .

我想我需要使用curl，这是我目前的方法:

$url1 = 'http://images.apple.com/global/nav/styles/navigation.css';
$curl1 = curl_init();       
curl_setopt($curl1, CURLOPT_URL, $url1); 
curl_setopt($curl1, CURLOPT_RETURNTRANSFER, TRUE); 
curl_exec($curl1); 
$contime1 = curl_getinfo($curl1, CURLINFO_TOTAL_TIME);

我从这个方法得到的值太大了(我正在与pingdom的值进行比较)。有人能告诉我合适的旋度函数吗，或者另一种计算方法?

使用microtime()函数

。

<?php
    $time = microtime(true);
    file('http://images.apple.com/global/nav/styles/navigation.css');
    echo "Time : ".(microtime(true) - $time)." Seconds";
?>

Time : 0.31984090805054 Seconds

$time = microtime(true); // Gets microseconds
file('http://images.apple.com/global/nav/styles/navigation.css');
echo "Time Elapsed: ".(microtime(true) - $time)."s";

使用microtime &文件获取内容

<?php
$url = 'http://images.apple.com/global/nav/styles/navigation.css';
$total_time = get_load_time($url) . '';
echo 'Data retrieved in ' . $total_time . ' seconds.';
function get_load_time($url) {
  $time1 = explode(' ', microtime());
  $start = $time1[1] + $time1[0];
  @file_get_contents($url);
  $time2 = explode(' ', microtime());
  $finish = $time2[1] + $time2[0];
  return round(($finish - $start), 4);
}
?>

//输出示例

Data retrieved in 1.7756 seconds.
