PHP add items from for loop to an object

Question

I'm sure this is trivial to an expert, I just don't know how to do it exactly.

I have a for loop

for ($x = 1; $x <= $picCount; $x++) {
    $finalUrl = $picUrl.$gsi.'&picfilename='.$vin.'_'.sprintf('%03d', $x) .'.jpg';
}

What I want to do is add each $finalUrl to the object or an array. How do I do that?

Example of final object:

stdClass Object
(
  [title] => Blah
  [test] => w00t!
  [picUrl] => array(
        http://example.com/image/xx1.jpg
        http://example.com/image/xx2.jpg
        http://example.com/image/xx3.jpg
        http://example.com/image/xx4.jpg
     )
)

So you are basically asking how to add a value to an array? Have you read any documentation or at least searched Stack Overflow? — Felix Kling

@FelixKling. I did, but I am looking to add an array from a for loop. I couldn't find what I was looking for — lz430

It doesn't matter from where an element is added from. The loop is irrelevant. If $foo is an array, then $foo[] = $bar; or array_push($foo, $bar) will append an element to that array. — Felix Kling

Simply set $finalUrl as an array:

$finalUrl = [];
for ($x = 1; $x <= $picCount; $x++) {
    $finalUrl[] = $picUrl.$gsi.'&picfilename='.$vin.'_'.sprintf('%03d', $x) .'.jpg';
}

So, assuming in the end you want an array of strings, this can be easily accomplished doing:

$a = [];
for ($x = 1; $x <= $picCount; $x++) {
    $finalUrl = $picUrl.$gsi.'&picfilename='.$vin.'_'.sprintf('%03d', $x) .'.jpg';
    $array[] = $finalUrl
}

return $a;

This will return an array of every $finalUrl values.

Breakdown:

$a = [] Initializes an array.

$a[] = $finalUrl Pushes $finalUrl to the array

$newArray = array();     // Will contain a list of $finalUrl
for ($x = 1; $x <= $picCount; $x++) {
    $finalUrl = $picUrl.$gsi.'&picfilename='.$vin.'_'.sprintf('%03d', $x) .'.jpg';
    $newArray[] = $finalUrl;
}

$newArray is the array of $finalUrl's created in the prior loop. print_r($newArray) will display it's contents.
