訪問dede后臺的時候提示Fatal error: Allowed memory size of 8388608 bytes exhausted問題的解決方法

解決方式一: ( 我用這方式就可以安裝了)

打開在.htaccess 文件裡 最上面開頭加上

php_value max_execution_time 1200

php_value memory_limit 200M

php_value post_max_size 200M

php_value upload_max_filesize 200M

解決方式二: (這我就不太會請高手解釋)

或者在httpd.conf主機配置里改

解決方式三: (這個我試過沒什麼作用..請高手幫忙解釋)

如出現這種問題則表明，程序運行占用的記憶空間超過了8M,解決方法修改PHP.ini文件將

memory_limit = 8M ;

的值改為12M就可以了

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:

ini_set("memory_limit","12M");

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.

如果是vps云主機，服務器用戶推薦大家采用第三種方法。
