如何确定是否通过cron /命令行加载PHP文件

I need to determine whether the PHP file is being loaded via cron or command line within the code. How can I do this?

我需要确定是否通过代码中的cron或命令行加载PHP文件。我怎样才能做到这一点？

4 个解决方案

#1

If you have control over the cron or command, have you considered passing a command-line argument, and reading it with $_SERVER['argv'][0]?

如果您可以控制cron或命令，您是否考虑过传递命令行参数，并使用$ _SERVER ['argv'] [0]读取它？

* * * * *   /usr/bin/php /path/to/script --cron

In the script:

在脚本中：

<?php
if(isset($_SERVER['argv'][0]) and $_SERVER['argv'][0] == '--cron')
   $I_AM_CRON = true;
else
   $I_AM_CRON = false;

#2

This is one simple way. Certain elements of the $_SERVER array are only set if called from HTTP. Thus you can:

这是一种简单的方法。仅当从HTTP调用时，才会设置$ _SERVER数组的某些元素。因此你可以：

if(!isset($_SERVER['REQUEST_METHOD'])){
 // from cron or command line
}else{
 // from HTTP
}

Others include: $_SERVER['HTTP_HOST']

其他包括：$ _SERVER ['HTTP_HOST']

The most reliable and exhaustive way to check where your script is run known to me is

检查脚本运行位置的最可靠和详尽的方法是

php_sapi_name()

php_sapi_name（）

Neither this nor any of the other listed methods listed here, however, will give you a distinction between "normal" CLI mode, and a cron call. gahooa's command line argument idea is probably the best and most reliable solution.

但是，此处列出的这个或任何其他列出的方法都不会让您区分“正常”CLI模式和cron调用。 gahooa的命令行参数思想可能是最好和最可靠的解决方案。

#4

You can check the PHP_SAPI constant to check if the CLI interpreter is being used:

您可以检查PHP_SAPI常量以检查是否正在使用CLI解释器：

$is_cli= PHP_SAPI == 'cli';

$ is_cli = PHP_SAPI =='cli';
