php running prompt: Fatal error Allowed memory size solution to insufficient memory, fatalallowed

The example in this article describes the solution to the PHP running prompt: Fatal error Allowed memory size. Share it with everyone for your reference. The specific method is as follows:

Some friends will encounter fatal error: Allowed memory size of 134217728 bytes exhausted when running a newly configured environment or a newly written program. One of these problems is caused by poor program writing, and the other is caused by the environment configuration. Bad things will also happen. For example, php5.1.27+apache2.2.3 seems to have a bug in Windows 2003. No matter how you fix it, you can't solve the problem of Fatal error Allowed memory size. You can only restart and configure the new environment and php version.

There are many solutions. Below we will introduce them according to the webmasters with different permissions.

1. Those with server management rights can modify the php.ini file

You can directly copy the code

in php.ini. The code is as follows: memory_limit = 8M;

increase to 12M or more. . (Note: M is followed by M, not MB)

2. For those who do not have server management rights

1. Modify the memory directly in php but your php needs to support the ini_set function. If this function is prohibited from being used in php.ini, then this method will be invalid.

Copy code The code is as follows:ini_set('memory_limit','12M');//Of course it can be set to a larger value

2.htaccess method, this is supported by general space hosts. Create an .htaccess file in the root directory and add the following content:

Copy code The code is as follows:

php_value memory_limit 20000000

Note: Generally speaking, 8M is the standard, but sometimes 8M is not enough.

Special reminder: Fatal error: Allowed memory size of 8388608 bytes exhausted, which means that the configured memory_limit value is 8M. The solution is also solved by the method introduced above. The memory_limit value must be debugged little by little.

I hope this article will be helpful to everyone’s PHP programming design.
