Understanding arrays

PHP
1

I have this bit if code to upload an image

<input type='file' name='file1' id='file1'>


if($_FILES['file1']['error'] > 0){
    die('An error ocurred when uploading.');
}
if(($_FILES['file1']['type'] != 'image/png') && ($_FILES['file1']['type'] != 'image/gif') && ($_FILES['file1']['type'] != 'image/jpeg') && ($_FILES['file1']['type'] != 'image/bmp'))
{
    die('Unsupported filetype uploaded.');
}
if($_FILES['file1']['size'] > 102400){
    die('File uploaded exceeds maximum upload size.');
}
$now = time(); 
while(file_exists($uploadFilename = 'uploads/'.$now.'-'.$_FILES['file1']['name'])) 
{ 
    $now++; 
} 
if(!move_uploaded_file($_FILES['file1']['tmp_name'], $uploadFilename)){
    die('Error uploading file - check destination is writeable.');
}

But i’d like to upload an array of images also, but am confused as what is the best way to do it if I simply make this change

<input type='file' name='image[]' id='file1'>

I really want to understand this process, so I gather I first need to check if an image has even been uploaded

if (!empty($_FILES['image'][]['name'])) {

then use a foreach statement to run code on each upload


//I really am confused at this point

Thanks…

If you’re wanting to upload multiple files the script processing them will need to rearrange the contents of the $_FILES array, there was a thread covering that a few months back, off-hand I can’t remember what the thread title was
