将数组导出为CSV失败:给定字符串 [英] Export an array to CSV failure: string given

问题描述

当我尝试将数组导出到CSV文件时，我无法解决出现的问题.我已经多次使用此功能了，但是没有出现错误.

I can't solve a problem occurring when I try to export an array to a CSV file. I have used this function several times without problem but here I do not see where my mistake is.

我设置了一个数组:

$mytags= array();

我通过循环填充它.当我通过 print_r($ mytags); 打印内容时似乎还可以，下面是我的输出示例:

I populate it by a loop. When I print the content through print_r($mytags); it seems to be OK, here some examples of my output:

Array ( [0] => [1] => air-travel [2] => airports [3] => security-airport [4] => city-airport  ... )

之后，我尝试通过fputcsv将结果导出到CSV:

After that I try to export the result to CSV by fputcsv:

$fp = fopen('file.csv', 'w');
foreach ($mytags as $fields) {
    fputcsv($fp, $fields);
}

但是我得到这个错误:

警告:fputcsv()期望参数2为数组，字符串为C:\ wamp \ www \ tests \ capturetags.php，第55行

Warning: fputcsv() expects parameter 2 to be array, string given in C:\wamp\www\tests\capturetags.php on line 55

问题可能是只有一个字段吗?另外，我尝试用 $ mytags 替换 $ fields 来编写CSV，在这种情况下，我得到了4GB的文件，所以它不是有人看到如何在CSV文件中记录其唯一字段吗?

Could the problem be that there is only one field? Alternatively, I tried to replace $fields by $mytags to write the CSV, and in this case I get a 4GB files, so it's not the Does someone see how to record thhis unique field in a CSV file?

推荐答案

错误非常明显， $ fields 不是数组，而是字符串.您需要一个数组.

The error is very clear, $fields is not an array, it is a string. You need an array.

fputcsv($fp, $mytags);

没有foreach循环将完成这项工作.

Without a foreach loop will do the job.
