How to post data to Firebase with a curl command using PHP

A very simply google search for your exact question lead me to a Stack Overflow post How to post data to firebase using PHP? with a solution.

Solution is:

1. = '{"id": "6"}'; 
2.  
3. = "https://test.firebaseio.com/test_api/types.json"; 
4. = curl_init(); 
5. curl_setopt(, CURLOPT_URL, );  
6. curl_setopt(, CURLOPT_RETURNTRANSFER, true); 
7. curl_setopt(, CURLOPT_POST, 1); 
8. curl_setopt(, CURLOPT_POSTFIELDS, ); 
9. curl_setopt(, CURLOPT_HTTPHEADER, array('Content-Type: text/plain')); 
10. = curl_exec(); 
11. if(curl_errno()) 
12. { 
13. echo 'Curl error: ' . curl_error(); 
14. } 
15. curl_close(); 

Firebase accept json object and you have to post as json object. E você pode usar Content-Type: application/x-www-form-urlencoded ou Content-Type: text/plain
