php - 获取 favicon.ico 时出现 504 网关超时错误

Question

我在一个虚拟主机共享帐户中，max_execution_time 默认为 120。我将它设置为 set_time_limit(0)，而 phpinfo() 中没有任何反应。有没有办法在网关超时错误出现之前防止或停止它？就像在 504 网关错误弹出窗口之前立即停止该过程一样。我正在获取 50 到 100 个网址中的图标。这是我的代码行。

<?php 
set_time_limit(0);
error_reporting(E_ERROR | E_PARSE);

function get_domain($url)
    {
      $pieces = parse_url($url);
      $domain = isset($pieces['host']) ? $pieces['host'] : '';
      if (preg_match('/(?P<domain>[a-z0-9][a-z0-9\-]{1,63}\.[a-z\.]{2,6})$/i', $domain, $regs)) {
        return $regs['domain'];
      }
      return false;
    }
