我们使用的是 PHP + FPM 8.2 + OPCache。以前我们使用https://www.repairrar.com/opcache.php来检查它的状态。但是今天它返回一个空页面。虽然它显示一个空页面，但我查看页面源代码发现它的内容大约有 3.3MB，但它们就是不显示在浏览器中。我尝试了 Chrome 和 FireFox，但显示的内容为空。
我还编写了一个小的 PHP 文件
<?php
echo '<pre>' , var_dump(opcache_get_status(false)) , '</pre>';
?>
当访问https://www.repairrar.com/opcache-get-status.php时，它显示 OpCache 已启用并正常运行：
