#userinfo.php
<?php
include_once("*****/prepend.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同级目录
use SebastianBergmannCodeCoverageCodeCoverage;
$coverage = new CodeCoverage;
 
$coverage->filter()->addDirectoryToWhitelist('/var/www/html/userinfo.php'); # 白名单<br>$coverage->filter()->removeDirectoryFromWhitelist('/var/www/html/userinfo.php'); # 从白名单中移除文件夹<br>$coverage->filter()->removeFileFromWhitelist('/var/www/html/userinfo.php'); # 从白名单中移除文件

$coverage->start('<Site coverage>');#开始统计
register_shutdown_function('__coverage_stop',$coverage);#注册关闭方法
 
function __coverage_stop(CodeCoverage $coverage){
 $coverage->stop();#停止统计
 $cov = '<?php return unserialize(' . var_export(serialize($coverage), true) . ');';#获取覆盖结果，注意使用了反序列化
 //echo $cov;
 file_put_contents(dirname(__FILE__).'/cov/site.' . date('U') .'.'.uniqid(). '.cov', $cov);#将结果写入到文件中
}
 
若多个域名或者接口请求要在同一个prepend文件里分别统计，在新建$coverage前加if条件即可，如
if(strpos($_SERVER['HTTP_HOST'],'www.baidu.com') === true){}

[root@mt-jry-01 html]# curl -d "user_id=10086" "127.0.0.1/userinfo.php"
