PHP - Read JS array in PHP

I have a very complicated array, and i want to convert it into a PHP valid array so i can loop through the values.

JS array:

$test = (       // Portraits
  {'image'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_t.jpg'},
  {'image'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_b.jpg', 'thumb'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_t.jpg'},
  {'image'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_t.jpg'});

EDIT

PHP loop: it should the image part for every value

  for ($i = 0;$i < $test.length;$i++){
    saveToDisk($test[$i]['image'],$i);
 }

Is the above correct? how can i read through the values?

You can use json_decode function to convert json formatted string into a PHP arrays (or object if you're calling it without the second parameter or with false instead)

$test = '[{"image":"http:\/\/farm8.staticflickr.com\/7319\/8993158058_f82968e61a_b.jpg","thumb":"http:\/\/farm8.staticflickr.com\/7319\/8993158058_f82968e61a_t.jpg"},{"image":"http:\/\/farm3.staticflickr.com\/2891\/8993155214_b8e091c625_b.jpg","thumb":"http:\/\/farm3.staticflickr.com\/2891\/8993155214_b8e091c625_t.jpg"},{"image":"http:\/\/farm8.staticflickr.com\/7432\/8993133146_d647438c55_b.jpg","thumb":"http:\/\/farm8.staticflickr.com\/7432\/8993133146_d647438c55_t.jpg"}]';

$array = json_decode($test, 1);

// Looping each inner array and printing image/thumb keys
foreach ($array as $arr) {
   echo $arr['image'].' - '.$arr['thumb'];
}

Also in order to convert your JavaScript object to a valid JSON string you should be using the JSON.strngify function:

JSON.stringify(object); // <-- JavaScript function

Your "array" code looks like an invalid mixture between PHP and Javascript syntax. It should look more like:

$test = json_decode("[
  {'image'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_t.jpg'},
  {'image'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_b.jpg', 'thumb'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_t.jpg'},
  {'image'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_t.jpg'}]");

Or better yet:

$test = [
  ['image'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7319/8993158058_f82968e61a_t.jpg'],
  ['image'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_b.jpg', 'thumb'=> 'http://farm3.staticflickr.com/2891/8993155214_b8e091c625_t.jpg'],
  ['image'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_b.jpg', 'thumb'=> 'http://farm8.staticflickr.com/7432/8993133146_d647438c55_t.jpg']
];
