How PHP modifies memory_limit memory limit

Today, my new server has installed the php environment, but the error "FatalError: Allowedmemorysizeofxxxxxxbytesexhausted" is prompted at runtime, which is due to insufficient memory.

Today, I have installed the php environment on my new server, but the Error "Fatal Error: Allowed memory size of xxxxxx bytes exhausted" is displayed at runtime. the memory is insufficient, next I will introduce several solutions to these problems.

Method 1: edit php. ini in php. ini.

Find the "memory_limit" item. if not, you can add this parameter at the end of the file. Below are some setting examples: memory_limit = 128 M; you can change m to any value you want to set.

Method 2:. htaccess

Note: This method takes effect only when php is executed using the Apache Module. Find ". htaccess file. if not, you can create one by yourself and put the following configuration into it:

Php_value memory_limit 128 M; you can change M to any value you want to set.

Method 3: modify the php memory settings at runtime

Add the following command line to your php code: ini_set ('memory _ limit ', '128m ');

Tip:If you use php5.2.17, the above method may not work for you. this official bug cannot solve some problems, and we can only reinstall the php environment, such as php5.4.
