在CSV文件

Question

我有一個是交給我一個CSV文件的位置後，刪除所有角色每天在年底的數據合併，我不需要這樣的：

"Date","Site","PCode","PName","Sales" 
    "2013/03/10 00:00:00","10195","66011","GT 1","9" 
    "2013/03/10 00:00:00","22413","66005","GT 2E","4" 
    "2013/03/10 00:00:00","10082","66003","GT 23E","6" 
    "SCode" 
    "12345678" 

我想運行PHP腳本，它刪除所有字符，包括和之後的「SCode」。文件中的位置和文件總長度每天都在變化，因此它需要來自單詞而不是來自設置的位置。

任何想法？我看了一下，但是大多數例子在一個不同的文件不會改變的設置位置之後移除。謝謝。

這樣的新文件：

"Date","Site","PCode","PName","Sales" 
    "2013/03/10 00:00:00","10195","66011","GT 1","9" 
    "2013/03/10 00:00:00","22413","66005","GT 2E","4" 
    "2013/03/10 00:00:00","10082","66003","GT 23E","6" 

從反饋下面都用這個感謝：

<? 
    $path="test.csv"; 
    $csv = file_get_contents($path); 

    $new_csv = strstr($csv,'"SCode"',true); //csv file up to "SCode" 

    $file = fopen("test2.csv","w"); 
    fwrite($file,$new_csv); 
    fclose($file); 
    ?> 

Answer 1

如果CSV文件是不是可笑的大，你可以使用strstr()功能，旗對於$before_needle設置爲true：

$csv; //your loaded in csv file as a string 

$new_csv = strstr($csv,'"SCode"',true); //csv file up to "SCode"
