How to extract and access data from JSON with PHP?
(1 answer)
Closed 4 years ago.
I am using the following code to pull data from an API with JSON results.
// Open connection
$ch = curl_init();
// Make the curl call
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$head = curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
$data = json_decode($head,true);
foreach($data as $item) {
$name = $item['name'];
$description = $item['description'];
echo "NAME: $name DESCRIPTION: $description";
}
If I use print_r($head) I see all of the results so I know url, username, password is good, however the echo statement at the end of the code is not producing results.
Here is a sample of what the JSON looks like when I print_r($head). Some of it at least.

Answer 1

After your decode, $data will have an array called events with each element being the array you are trying to look at. try:
foreach ($data['events'] as $item)...

Answer 2

print_r() does not make sense forstring, but only for array and object.
it might be rather alike this (and maybe you have to use $data['events'] instead)
when using $data = json_decode($response); it would be $data->events:
$data = json_decode($response, true);
// die('<pre>'.print_r($data, true).'</pre>');
foreach($data['events'] as $key => $item) {
// $event_id = $data['events'][$key]['eventId'];
$event_id = $item['eventId'];
// $name = $data['events'][$key]['name'];
$name = $item['name'];
// $desc = $data['events'][$key]['description'];
$desc = $item['description'];
echo "KEY: $key, ID: $event_id, NAME: $name, DESCRIPTION: $desc";
}
those inline comments just indicate, what is actually being accessed.
