I am new to programming and would like to begin adding more advanced applications to my site. I am trying to call an api with php. I'm having trouble getting it to return json format.
<?php
if(!empty($_GET['hospital_name'])) {
$Hospcomp_url = 'https://data.medicare.gov/resource/rbry-mqwu.json?hospital_name=' . urlencode($_GET['hospital_name']);
$Hospcomp_json = file_get_contents($Hospcomp_url);
json_decode($Hospcomp_json, true);
}
?>
<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="utf-8">
<title>CMS</title>
</head>
<body>
<form action="">
<input type="text" name="hospital_name"><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
It seems, you get your result properly but you don't do anything with it. First of all, you don't assign the array decoded from JSON to a variable. And then, you don't echo or process your array otherwise.
Please replace this:
json_decode($Hospcomp_json, true);
with something like this:
$decoded = json_decode($Hospcomp_json, true);
var_export($decoded);
Then you'll have your output and you will be able to decide what to do next.
Calls are correct, just var_export it.
if(!empty($_GET['hospital_name'])) {
$Hospcomp_url = 'https://data.medicare.gov/resource/rbry-mqwu.json?hospital_name=' . urlencode($_GET['hospital_name']);
$Hospcomp_json = file_get_contents($Hospcomp_url);
var_export(json_decode($Hospcomp_json, true));
}
