To run a PHP file on the background, you must put your code in one file and call the PHP interpreter to run it on the background. On a *nix server, use exec( '/usr/bin/php -f path/to/your/script > /dev/null &' );. Check the path to the PHP interpreter on your server, it might be something else than /usr/bin/php, ask your hosting provider if necessary. On a Windows server, use pclose( popen( 'start /b C:\php\php.exe -f path\to\your\script' ) ); (again, assuming that php.exe is in C:\php).

要在后台运行PHP文件,必须将代码放在一个文件中,并调用PHP解释器在后台运行它。在* nix服务器上,使用exec('/ usr / bin / php -f path / to / your / script> / dev / null&');.检查服务器上PHP解释器的路径,它可能是/ usr / bin / php之外的其他东西,如有必要,请询问您的托管服务提供商。在Windows服务器上,使用pclose(popen('start / b C:\ php \ php.exe -f path \ to \ your \ script')); (再次,假设php.exe在C:\ php中)。

The background process, however, cannot output anything to the user's browser, since it's running on its own. One way to accomplish what you need would be to output the PHP results in a file, set some flag when the job is done, and in another script check if the results are ready and give a link to the file for the user.

但是,后台进程无法向用户的浏览器输出任何内容,因为它自己运行。实现所需要的一种方法是将PHP结果输出到文件中,在作业完成时设置一些标志,在另一个脚本中检查结果是否准备就绪,并为用户提供文件链接。
