Currently this what im trying
$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:
$decoded=json_decode($gifs);
Then use the following loop:
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.
