好吧,所以我在过去的3个小时里一直在讨论这个问题,并且一直在谷歌上搜索,没有解决问题.所以,我写了一个示例脚本来重现这个,因为我的原始脚本大约是800行.
<?php
set_time_limit(0);
ini_set('max_input_time', '-1');
ini_set('max_execution_time', '0');
error_log("executing script... ");
$time = time();
for ($t = 0; $t <= 15; $t++) {
error_log("Logging: $t (".(time()-$time)." seconds)");
sleep(5);
}
error_log("execution done (".(time()-$time)." seconds)");
?>
现在,sleep函数只是用于重新创建页面的执行时间,而不是在原始代码中使用.这将在error_log文件中生成以下结果

继承了phpinfo的一些相关设置
=== apache2handler ===
Max Requests: Per Child: 1000 - Keep Alive: on - Max Per Connection: 200
Timeouts: Connection: 300 - Keep-Alive: 2
=== PHP Version 5.4.5 Core Settings ===
max_execution_time Local: 0 Master: 30
max_input_time Local: -1 Master: -1
我已经尝试了我能想到的一切.它似乎是使用Apache或PHP的服务器设置,因为当我在我的localhost上运行相同的脚本时,它会成功执行,而不需要双重加载.在它问之前,是的,每当我进行INI更改或apache配置更改时,我一直在重新启动apache.
另外,这是上面例子的access_log条目.

在执行时间达到60秒时肯定有这样的事情,因为当我将执行时间改为55秒时,它会运行一次就好了.

任何帮助都将非常感谢!
像缺少的图标这样的东西会导致你的脚本被调用两次.请参阅http://www.webdeveloper.com/forum/showthread.php?245809-Script-Running-Twice.如果您将非www重定向到www或反之亦然,它也可以.当从非www重定向到www时,请参阅PHP在页面加载时执行两次
