I attempted using the if(is_array()) function, but instead of getting an error message, the h1 heading just kept appearing. I checked my code on phpcodechecker and it showed no issues, but when I run it on my browser, I keep encountering an "invalid argument for the foreach()" error. I even tried changing $json to $jsondata, but that didn't solve the problem either. Can someone help me understand why this foreach loop is returning an invalid argument?
<?php
$jsondata = file_get_contents("movies.json");
$json = json_decode($jsondata, true);
?>
