Array within Array (for each)

[George Botley]

Hi,

 

 

Here's the array under the $img variable

 

 

Array ( [0] => Array ( [url] => IMG_0002.JPG ) ) 1 

 

It would normally have multiple values, depending on the amount the users adds to the form.

 

 

Basically, for key '0' on the array I wish to then get the value of the sub array "url".

 

 

How would I do this in a foreach loop?

 

George.

this will grab each entry in the array, and then you pull the named key (url) for that entry and do what you want, along with any other keys. it is best if your keys are always the same.

<?php
foreach ($array as $entry){
echo $entry['url']; // named array key in nested array
}
?>

 

or this will cycle through each entry, and then each value in the entry. it's cumbersome and not recommended unless you need to process each value THE SAME, separately.

 

<?php
foreach ($array as $entry){
foreach ($entry as info) {
// do something with each piece of info, in each entry
}
}
?>
