PHP：CSV到数组，数组到HTML

Question

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];
}
