PHP:CSV到数组,数组到HTML

I have converted an one-column CSV into a PHP associative array with the following code:

$file = array_map('str_getcsv', file('file.csv'));

And now I have something like this:

Array ( 
[0] => Array ( [0] => Value 1 ) 
[1] => Array ( [0] => Value 2 ) 
[2] => Array ( [0] => Value 3 )
.
.
.
[i] => Array ( [0] => Value i )
)

How can I put those values into a HTML form? I have tried it using foreach ($file as $pos => $pos2 => $pos3) to declare the loop, but the form still shows "Array" as output.

Also, is there any way to get a simple numeric array from this CSV?

图片转代码服务由CSDN问答提供 功能建议

我已将单列 CSV转换为PHP关联数组,其代码如下 :

  $ file = array_map('str_getcsv',file('file.csv')); 
   
 
 

现在我有类似的东西:

  Array(
 [0] => Array([0] => Value 1)
 [1] =  >数组([0] =>值2)
 [2] =>数组([0] =>值3)
。
。
。
 [i] =>数组 ([0] =>值i)
)
   
 
 

如何将这些值放入HTML表单中? 我尝试使用 foreach($ file as $ pos => $ pos2 => $ pos3)来声明循环,但表单仍显示“Array”作为输出。

此外,有没有办法从这个CSV中获取一个简单的数字数组?

    As you have array of arrays and you need values under key 0 in each subarray, your code can be:

    foreach ($file as $pos) {
        echo $pos[0];
    }
