PHP run a curl command - php

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

Answer 1

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:

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);
