我的 php 代码只是将我的 csv 文件的第一行导入数据库

【中文标题】我的 php 代码只是将我的 csv 文件的第一行导入数据库

【英文标题】：my php code is only importing the first line of my csv file to the database

【问题描述】：

所以，我有一个要导入数据库的 csv 文件，但它只导入第一行。 我不知道为什么它不导入我的 csv 文件中的所有数据。 可能是换行的原因？

我的 CSV 文件示例：

“蒂亚戈”,20,11,sip/11,20,w,2016-03-01 14:33:06,2016-03-01 14:33:09,2016-03-01 14 :33:51,45 "克劳迪奥" ,10,11,sip/11,20,w,2016-03-01 14:35:05,2016-03-01 14:35:07,2016-03-01 14:35: 48,43 “Hortencio”,11,21,sip/21,20,w,2016-03-01 14:39:55,2016-03-01 14:40:12,2016-03-01 14:40: 25,30 “安德烈”,19,22,22000@default,s,2016-03-01 14:43:22,2016-03-01 14:43:42,2016-03-01 14:43:42, 20

【问题讨论】：

$linecount=count(file($path.''.$filename.'.csv')); 将始终等于 1。它只是在计算数组中的条目数，即一个...

【参考方案1】：

您必须遍历每一行才能读取整个文件，否则您只会读取文件中的第一行

`

$file = fopen($path.''.$filename.'.csv', "r");
$csv = array();  
while (($csv = fgetcsv($file, 0, ",", ' ')) !== FALSE) 

   $n[] = $csv;

fclose($file);

`

感谢您的帮助我解决了它，如果您的代码现在感谢它提供了所有数据

现在只需要知道导入数据库

你应该在循环内写“INSERT”查询
