There is a mix of JSON and PHP-serialized data.
<?php
$string = '{"num_rows":2,"row":{"setting":"a:6:{s:4:\"name\";s:9:\"Featutred\";s:7:\"product\";a:2:{i:0;s:3:\"145\";i:1;s:3:\"148\";}s:5:\"limit\";s:1:\"5\";s:5:\"width\";s:3:\"200\";s:6:\"height\";s:3:\"200\";s:6:\"status\";s:1:\"1\";}"},"rows":[{"setting":"a:6:{s:4:\"name\";s:9:\"Featutred\";s:7:\"product\";a:2:{i:0;s:3:\"145\";i:1;s:3:\"148\";}s:5:\"limit\";s:1:\"5\";s:5:\"width\";s:3:\"200\";s:6:\"height\";s:3:\"200\";s:6:\"status\";s:1:\"1\";}"},{"setting":"a:6:{s:4:\"name\";s:17:\"Featured Products\";s:7:\"product\";a:2:{i:0;s:3:\"145\";i:1;s:3:\"146\";}s:5:\"limit\";s:1:\"4\";s:5:\"width\";s:3:\"200\";s:6:\"height\";s:3:\"200\";s:6:\"status\";s:1:\"1\";}"}]}';
$dataObject = json_decode($string);
foreach($dataObject->rows as $row){
$productData = unserialize($row->setting);
print_r($productData);
}
Will result in
Array
(
[name] => Featutred
[product] => Array
(
[0] => 145
[1] => 148
)
[limit] => 5
[width] => 200
[height] => 200
[status] => 1
)
Array
(
[name] => Featured Products
[product] => Array
(
[0] => 145
[1] => 146
)
[limit] => 4
[width] => 200
[height] => 200
[status] => 1
)
NOTE: There is no error checking in code above, since it is written for your particular example. If you are not sure that your input data is correct (that is usual), you need to check if JSON is ok, object is object and also has needed properties, etc.
