本地主機和服務器之間的內存分配和利用差異 - PHP

Question

我有一個PHP腳本，其中我正在讀取一個csv並將值導入數組進行計算。我已經使用WAMP在本地主機上構建了這個大腳本，並且一切正常。我已經把它變成一個Web服務器現在正在通過接收大約一半的內存錯誤（我沒有在本地主機接收）

解決，我已經把下面的代碼貫穿於我的代碼段：

echo memory_get_usage(); 

並已註釋掉所有部分，並一直工作直到它出錯。

段1，我有內存分配2.16 MB的本地主機和1.29 MB的網絡服務器。 在第二段，我有內存分配2.32 MB的本地主機和1.57 MB的網絡服務器。

然而上段三個I得到本地主機3.32 MB，但對於服務器我得到以下錯誤：

Fatal error: Out of memory (allocated 326631424) (tried to allocate 71 bytes) in /home/blablabla

沒有任何人有一個想法是什麼會導致此？該文件來自同一個目錄，這裏是下面的代碼。這是一個足球計算器，讀取歷史統計數據來計算幻想足球積分，只有194線長

我不是一個很好的程序員，我正在使用這個項目來從根本上學習我的第一個語言。這是我寫的第一部分代碼，所以我確信它需要重新編寫（而且我可能會這麼做），但是我沒有看到錯誤會導致這種情況。它是我創建的陣列的數量？爲什麼它會在localhost而不是web服務器上運行？使用siteground作爲託管

感謝您對任何人抽出時間

不完全確定的代碼本身，而是內存分配也不是一成不變的。僅僅因爲本地機器上的WAMP設置爲處理內存使用情況並不意味着在您的Web服務器上安裝PHP。

我會建議設置一個phpinfo文件並將您的WAMP版本的php與您的託管版本進行比較。你應該能夠快速看到兩者之間的差異。您可以設置您的本地WAMP安裝以匹配您的託管版本，或者讓您的虛擬主機更改它們。

如果您在共享服務器上，但您值得一試，您可能不會在託管端獲得太多運氣。

希望有助於一些。
