PHP - Assigning An Uploaded Image To Recall In A Php Array!! Really Need Help !!!

I need to assign unknown array keys and their values to strings.

The code I am using is:
Code: [Select]
$cart = $_SESSION['cart'];
$items = explode(',',$cart);
$qty = array();


foreach ($items as $item) {
$qty[$item] = $qty[$item] + 1;
}
print_r($qty);
The keys change and are not ordered. I do not know what the key or it's value may be.  So as an example, I might have:
Code: [Select]
Array ( [2] => 5 [4] => 8 ) or in a different scenario, I might have:
Code: [Select]
Array ( [1] => 6 )
What those numbers represent is a product id (the key), and the quantity (the value of the key).

Can someone help me to assign these to a string?  I have been reading all morning, and not making any progress. 

Thank you!

Hi all,

I can't seem to designate an array key by using a variable and I was wondering if this is possible. I'm looking to do something like this:

Code: [Select]

<?php
$key = "apple";
$arr = array($key => "fruit");
?>
Any suggestions would be appreciated!

Hey everyone. I have been trying to assign dates to image so I could sort them, and also display the date they were uploaded. But I need some help. I have a script that uploads an image to a file directory, and also stores the file directory and the upload date in a database. And I also have a script that displays the images in the file directory but I cannot find a way to assign the right date to the right image.
Here is the script that displays the images:

Code: (php) [Select]
if (isset($_POST['submit'])) {
// fill an array with all items from a directory
$dir = "thumbs/";

$handle = opendir($dir);
while ($file = readdir($handle)) {
$files[] = $file;

// This removes the full stops from the array
unset($files[0]);
unset($files[1]);
               
}   
            foreach($files as $fileimg)
{

echo "<img src='". $dir . $fileimg ."'/>\n";
                echo "$date";
}
       
}
and here is the script for calling the date from the database:

Code: [Select]
$query = mysql_query("SELECT imgaddress, uploaddate FROM thumbs WHERE imgaddress='" . $dir . $file . "'");

                if (mysql_num_rows($query) == 1) {
                     $row = mysql_fetch_assoc($query);

                     $date = $row['uploaddate'];
If I use the database statement before the foreach, then it does not get the right file directory, but if I call it inside the foreach, then I cannot use krsort() to sort the array.

Any help would be greatly appreciated, thanks

What I want to achieve is this;

When a record is being inserted, a user will make a selection from the dropdown box with a list of directories. Then, a user will upload an image. When a image is uploaded and a directory is chosen, I want the image to be assigned to a specific directory from the list so when the record is inserted, that image will be placed in the specific directory. How do I achieve this please?

Hi. I have a script here that will let users upload an image to my website but I just can't figure out how to save the uploaded image as "upload/logo.png" so that it will replace the already existing "upload/logo.png".
Help would be greatly appreciated.
