PHP在我的所有腳本運行內存

我的php.ini擁有256MB內存集：

;;;;;;;;;;;;;;;;;;; 
; Resource Limits ; 
;;;;;;;;;;;;;;;;;;; 

max_execution_time = 250  ; Maximum execution time of each script, in seconds 
max_input_time = 120 ; Maximum amount of time each script may spend parsing request data 
;max_input_nesting_level = 64 ; Maximum input variable nesting level 
memory_limit = 256MB ; Maximum amount of memory a script may consume (256MB)

於是我只好這是不是寫得很好了一定的PHP腳本，當我執行它PHP的內存不足，我的電腦凍結。在運行腳本之前，我已經增加了php.ini中的內存限制。之後，我已將其更改回默認值。

現在的問題是，它似乎已經做了一些我的PHP安裝。我現在執行的每個PHP腳本都告訴我它沒有足夠的內存。之前運行過的腳本沒有問題。

看起來好像我之前提到的那個壞腳本仍然以某種方式在後臺運行。

我重新啓動PHP，Apache，我已經重新啓動我的電腦，甚至睡了8個小時。第二天早上我發現所有的PHP腳本仍然內存不足。我勒個去？

我收到了這樣的錯誤，現在到處（有當然的錯誤改變文件） - 與每一個哪怕是最簡單的PHP腳本：

Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 6144 bytes) in D:\data\o\WebLib\src\Db\Db.php on line 241

Fatal error (shutdown): Allowed memory size of 262144 bytes exhausted (tried to allocate 6144 bytes) in D:\data\o\WebLib\src\Db\Db.php on line 241

確定這裏是腳本（我已經註釋掉壞的部件）：

我們能看到劇本嗎？ – yoda 2011-01-28 07:17:52

你不能在php.ini中增加允許的內存大小嗎 – Gaurav 2011-01-28 07:21:51

看起來很清楚你的內存設置不正確。嘗試在您的配置中使用「256M」而不是「256MB」。 – 2011-01-28 07:31:28
