dede后台出现Fatal error: Allowed memory size of 83解决方

今天在采集数据的时候,网站突然出现了Fatal error: Allowed memory size of 8388608 bytes,在百度查了下,发现是程序运行占用的记忆空间超过了8M,网上主流的方法有三种:


解决方式一: ( 我用这方式就可以安装了)

打开在.htaccess 文件裡 最上面开头加上

php_value max_execution_time 1200
php_value memory_lim

解决方式二: (这我就不太会请高手解释)


解决方式三: (这个我试过没什麽作用..请高手帮忙解释)


memory_limit = 8M ;

This error message can spring up in a previously functional PHP script when the memory requirements exceed the default 8MB limit. Don’t fret, though, because this is an easy problem to overcome.To change the memory limit for one specific script by including a line such as this at the top of the script:

The 12M sets the limit to 12 megabytes (12582912 bytes). If this doesn’t work, keep increasing the memory limit until your script fits or your server squeals for mercy.
You can also make this change permanently for all PHP scripts running on the server by adding a line like this to the server’s php.ini file:
memory_limit = 12M
Keep in mind that a huge memory limit is a poor substitute for good coding. A poorly written script may inefficiently squander memory which can cause severe problems for frequently executed scripts. However, some applications are run infrequently and require lots of memory like importing and processing a big data file.
