PHP file (for example, my_lengthy_script.php)
PHP 文件（例如，my_lengthy_script.php）
ini_set('max_execution_time', 300); //300 seconds = 5 minutes
.htaccess file
.htaccess 文件
<IfModule mod_php5.c>
php_value max_execution_time 300
</IfModule>
More configuration options
更多配置选项
<IfModule mod_php5.c>
php_value post_max_size 5M
php_value upload_max_filesize 5M
php_value memory_limit 128M
php_value max_execution_time 300
php_value max_input_time 300
php_value session.gc_maxlifetime 1200
</IfModule>
If wordpress, set this in the config.php file,
如果是 wordpress，请在 config.php 文件中进行设置，
define('WP_MEMORY_LIMIT', '128M');
If drupal, sites/default/settings.php
如果是drupal，sites/default/settings.php
ini_set('memory_limit', '128M');
If you are using other frameworks,
如果您正在使用其他框架，
ini_set('memory_limit', '128M');
You can increase memory as gigabyte.
您可以将内存增加为千兆字节。
ini_set('memory_limit', '3G'); // 3 Gigabytes
259200 means:-
259200 意味着：-
( 259200/(60x60 minutes) ) / 24 hours ===> 3 Days

Well, since your on a shared server, you can't do anything about it. They usually set the max execution time so that you can't override it. I suggest you contact them.
好吧，由于您在共享服务器上，因此您无能为力。他们通常设置最大执行时间，以便您无法覆盖它。我建议你联系他们。

well, there are two way to change max_execution_time.
1. You can directly set it in php.ini file.
2. Secondly, you can add following line in your code.

1.可以直接在php.ini文件中设置。
2. 其次，您可以在代码中添加以下行。

Use mod_php7.cinstead of mod_php5.cfor PHP 7
在 PHP 7 中使用mod_php7.c而不是mod_php5.c
Example
例子
<IfModule mod_php7.c>
php_value max_execution_time 500
</IfModule>

Try to set a longer max_execution_time:
尝试设置更长的时间max_execution_time：
<IfModule mod_php5.c>
php_value max_execution_time 300
</IfModule>
<IfModule mod_php7.c>
php_value max_execution_time 300
</IfModule>

This is old question, but if somebody finds it today chances are php will be run via php-fpm and mod_fastcgi. In that case nothing here will help with extending execution time because Apache will terminate connection to a process which does not output anything for 30 seconds. Only way to extend it is to change -idle-timeout in apache (module/site/vhost) config.
这是个老问题，但如果今天有人发现它，很可能 php 将通过 php-fpm 和 mod_fastcgi 运行。在这种情况下，这里没有任何东西可以帮助延长执行时间，因为 Apache 将终止与 30 秒内不输出任何内容的进程的连接。扩展它的唯一方法是更改 apache（模块/站点/虚拟主机）配置中的 -idle-timeout。
FastCgiExternalServer /usr/lib/cgi-bin/php7-fcgi -socket /run/php/php7.0-fpm.sock -idle-timeout 900 -pass-header Authorization

There's probably a limit set in your webserver. Some browsers/proxies will also implement a timeout. Invoking long running processes via an HTTP request is just plain silly. The right way to solve the problem (assuming you can't make the processing any faster) is to use the HTTP request to trigger processing outside of the webserver session group then poll the status via HTTP until you've got a result set.
您的网络服务器中可能设置了限制。一些浏览器/代理也会实现超时。通过 HTTP 请求调用长时间运行的进程是很愚蠢的。解决问题的正确方法（假设您不能使处理速度更快）是使用 HTTP 请求触发 Web 服务器会话组之外的处理，然后通过 HTTP 轮询状态，直到您获得结果集。
