PHP run a curl command

Question

I have this curl code

curl -X POST https://url.com -H 'authorization: Token YOUR_Session_TOKEN' -H 'content-type: application/json' -d '{"app_ids":["com.exmaple.app"], "data" : {"title":"Title", "content":"Content"}}

that is used for push notification from web service to a mobile application. How can I use this code in PHP? I can't understand the -H and -d tags

If you have terminal you can then try the following command curl --help. You will find those flags. -H flag for setting header and -d flag for setting http post data. — unclexo

You can use this website to convert any of such: https://incarnate.github.io/curl-to-php/

But basically d is the payload (the data which you send with the request: usually POST or PUT); H stands for headers: each entry is another header.

So the most 1-to-1 example would be:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://url.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"app_ids\":[\"com.exmaple.app\"], \"data\" : {\"title\":\"Title\", \"content\":\"Content\"}}");

$headers = array();
$headers[] = 'Authorization: Token YOUR_Session_TOKEN';
$headers[] = 'Content-Type: application/json';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);

but you can make it more dynamic and easy to manipulate based PHP variables by first creating an array with the attributes and then encoding it:

$ch = curl_init();

$data = [
    'app_ids' => [
        'com.example.app'
    ],
    'data' => [
        'title' => 'Title',
        'content' => 'Content'
    ]
];

curl_setopt($ch, CURLOPT_URL, 'https://url.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));

$headers = array();
$headers[] = 'Authorization: Token YOUR_Session_TOKEN';
$headers[] = 'Content-Type: application/json';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);

I suggest reading the manual of php-curl: https://www.php.net/manual/en/book.curl.php

You may also do it in the following way:

<?php
$url = "http://www.example.com";

$headers = [
    'Content-Type: application/json',
    'Authorization: Token YOUR_Session_TOKEN'
];

$post_data = [
    'app_ids' => [
        "com.exmaple.app"
    ],
    'data' => [
        'title' => 'Title', 
        'content' => 'Content'
    ],
];

$post_data = json_encode($post_data);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($ch);

// For debugging
$info = curl_getinfo($ch);

curl_close($ch);

echo '<pre>';
print_r($response);
