PHP在我的所有脚本中耗尽内存

Question

编辑:

我的php.ini有256MB内存集:

;;;;;;;;;;;;;;;;;;;
; 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)

所以我有一个PHP脚本编写得不是很好,当我执行它时,PHP内存不足,我的PC冻结了.在运行脚本之前,我已经增加了php.ini中的内存限制.之后我将其更改回默认值.

现在问题是它似乎已经为我的PHP安装做了一些事情.我现在执行的每个PHP脚本都告诉我它没有足够的内存.以前运行过的脚本没有问题.

看起来我之前提到的一个糟糕的脚本仍然在某种程度上在后台运行.

我重新启动了PHP,Apache,我重新启动了我的电脑,甚至睡了8个小时.接下来的事情我发现所有的PHP脚本仍然没有内存.我勒个去？

我现在到处都是这样的错误(当然错误更改中的文件) - 每一个甚至最简单的PHP脚本:

致命错误:第241行的D:\ data\o\WebLib\src\Db\Db.php中允许的内存大小为262144字节(试图分配6144字节)

致命错误(关闭):第241行的D:\ data\o\WebLib\src\Db\Db.php中允许的内存大小为262144字节(试图分配6144字节)

好的是脚本(我已经注释掉了坏的部分):

Answer 1

更改php.ini:

memory_limit = 256M

请注意,您不应该使用MB或KB,而是使用M或K.
