#userinfo.php

$id = $_POST["user_id"];
if ($id != 10086){
 exit();
}
$userinfo = array(
 'username'=>'jason',
 'password'=>'123456',
);
$result = array(
  'code'=>10000,
  'message'=>"success",
  'data'=>$userinfo,
 );
echo json_encode($result);

#prepend.php
?php
require_once dirname(__FILE__).'/vendor/autoload.php'; # 在composer生成的vender同級目錄
use SebastianBergmann\CodeCoverage\CodeCoverage;
$coverage = new CodeCoverage;
 
$coverage->filter()->addDirectoryToWhitelist('/var/www/html/userinfo.php'); # 白名單br>$coverage->filter()->removeDirectoryFromWhitelist('/var/www/html/userinfo.php'); # 從白名單中移除文件夾br>$coverage->filter()->removeFileFromWhitelist('/var/www/html/userinfo.php'); # 從白名單中移除文件

$coverage->start('Site coverage>');#開始統(tǒng)計
register_shutdown_function('__coverage_stop',$coverage);#注冊關(guān)閉方法
 
function __coverage_stop(CodeCoverage $coverage){
 $coverage->stop();#停止統(tǒng)計
 $cov = '?php return unserialize(' . var_export(serialize($coverage), true) . ');';#獲取覆蓋結(jié)果，注意使用了反序列化
 //echo $cov;
 file_put_contents(dirname(__FILE__).'/cov/site.' . date('U') .'.'.uniqid(). '.cov', $cov);#將結(jié)果寫入到文件中
}
 
若多個域名或者接口請求要在同一個prepend文件里分別統(tǒng)計，在新建$coverage前加if條件即可，如
if(strpos($_SERVER['HTTP_HOST'],'www.baidu.com') === true){}
