为什么小弟我PHP函数执行问没有释放内存
为什么我PHP函数执行问没有释放内存
最近做一个导入大文件，因为涉及到要对文件处理得到需要的结构的数据。
把大量数据保存在数组中。
在处理的过程中，消耗很大内存，不是memory_limit设置问题，我已经设置足够大。
处理过程中自己也有unset掉不要的。但是通过memory_get_usage()输出函数调用前跟调用后的内存对比。
发现函数调用后，内存并没有明显的下降。那些大数组都已经unset掉了。也是一样。
如果导入的文件量不大，不会出现内存溢出的错误提示。但是当文件大到一定程度。就因为执行过程中，
函数调用完，内存还是占用很大。而导致内存溢出。
这个让我有点郁闷了。函数调用完不是都释放了局部变量空间了吗？
是不是什么内存泄露，有人遇到相同问题吗。希望有遇到相同问题的或者有人知道的。一起来讨论下。谢谢。
ps：分数蛮少的，只能这样了。
