Getting individual data from an array

[richiejones24]

I am having problems displaying individual data I am using  $filename[0] to display the first data, any ideas where i am going wrong. 

 

<?php

$active_keys = array();
foreach($_POST['img'] as $key => $filename)
{
    if(!empty($filename))
    {
        $active_keys[] = $key;
    }

echo "". $filename[1];
}





?>

is $_POST['img'] an array?

[richiejones24]

yes it is

if i use $filename by itself i can everything in the array is i know it is working but when i use $filename[0] i get nothing

$filename is only supposed to be a temporary holder for each value of $_POST['img'] while looping through it.

 

After the loop, $filename will hold the last value of $_POST['img']. If that's not an array, $filename[1] will output the 2nd character of the last value of $_POST['img'].

 

Since I'm not sure what you're trying to do, I can't help you. My guess is, you wanted this

 

$_POST['img'][ $active_keys[0] ]

 

That will return the first populated value of $_POST['img], assuming it exists.
