JavaScript
$gifs=file_get_contents(__DIR__ ."/backend_web/Json/tags/test.txt");$local=$gifs; $decoded=json_decode($gifs,true);//print_r($decoded);foreach ($decoded as $y) {foreach ($y->images as $z) { $data = $z->link }}but getting this error . Notice: Trying to get property ‘link’ of non-object in C:xampphtdocstesttest.php on line 29 Any help would be much appreciated

Answer
Better work with objects than arrays:
JavaScript
$decoded=json_decode($gifs);Then use the following loop:
JavaScript
foreach ($decoded->data->items as $y) { if (isset($y->images)) { foreach ($y->images as $x) { $data = $x->link; } }}Some objects have no “images” property, that’s why you get the error. It’s eliminated by the isset function.
