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?

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];
}

  • I think the op is missing understanding in how array and foreach works. This solution seems clear to me but i'm not sure he will get it. – Unex Dec 05 '17 at 17:16
  • If I fully understand `foreach` and arrays in PHP I wouldn't be here asking this question, but of course I get the solution provided by @u_mulder . I'm not that stupid, thanks. – anxoestevez Dec 05 '17 at 17:45
  • Thank you so much @u_mulder . It works like a charm. – anxoestevez Dec 05 '17 at 17:46
