when echoing renamed file its showing single character - php

Question

I am slowly working on a image uploader, and wondering why when echoing my renamed files, its giving me a single character instead of the whole thing.
Any reason it would be doing that?
It does tho, successfully upload the image as a phil_546d196082606.jpg with a different number for each image
Here is my code
<?php
if (isset($_POST['addpart'])) {
$image = $_FILES['images']['tmp_name'];
$name = $_POST['username'];
$i = 0;
foreach ($image as $key) {
$fileData = pathinfo(basename($_FILES["images"]["name"][$i]));
$fileName = $name .'_'. uniqid() . '.' . $fileData['extension'];
move_uploaded_file($key, "image/" . $fileName);
copy("image/" . $fileName, "image_thumbnail/" . $fileName);
$i++;
}
echo 'Uploaded<br>';
$fileName1 = $fileName[0];
$fileName2 = $fileName[1];
$fileName3 = $fileName[2];
echo 'Main Image - '.$fileName1.'<br>';
echo 'Extra Image 1 - '.$fileName2.'<br>';
echo 'Extra Image 2 - '.$fileName3.'<br>';
echo '<hr>';
}
?>

Answer 1

$filename is a string and strings in php are arrays where each letter has an index $filename[o] is the first letter and so on.Use
$filename[]=$name .'_'. uniqid() . '.' . $fileData['extension'];

Answer 2

Try the below block of code
$fileName[] = $name .'_'. uniqid() . '.' . $fileData['extension'];
move_uploaded_file($key, "image/" . end($fileName));
copy("image/" . end($fileName), "image_thumbnail/" . end($fileName));

Answer 3

$fileName = $name .'_'. uniqid() . '.' . $fileData['extension'];
Filename is the string. It is : $name . number.
Like philip12345.
So if we have:
philip
012345
$fileName[0] = p
$fileName[1] = h
Also you overwrite filename in each loop. Try to save it to an array and print it, here is some code:
$fileNames = array();
foreach ($image as $key)
{
$fileName = $name .'_'. uniqid() . '.' . $fileData['extension'];
fileNames[$i] = $fileName;
}
echo $fileNames[0];
echo $fileNames[1];
echo $fileNames[2];
You could also use a foreach loop to go over the array with the filenames and print each element, this is cool because it will works with any number of images, not just 3:
foreach ($fileNames AS $key2)
{
echo ($key2);
}
