CartoDB - SQL API - Post request with php - php

Question

In my app I'd like to send some small amount of data to my cartodb-table with my php-script.
I would like to use the SQL-API. My app parse the data in the form like:
https://{account}.cartodb.com/api/v2/sql?q=INSERT INTO test_table (column_name, column_name_2, the_geom) VALUES ('this is a string', 11, ST_SetSRID(ST_Point(-110, 43),4326))&api_key={Your API key}
I tried several functions http_get, file_get_contents, http_request but nothing pass the data to my account. Put when I copy/paste the URL and open in the browser, everything is added.
What's the right function? There so many different ones... PHP-HTTP-Functions
EDIT
With the code from this solution I get this error, when I print out the response:
{"error":["syntax error at end of input"]}
within the browser I get this:
{"rows":[],"time":0.038,"fields":{},"total_rows":1}
my request code right now:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $fullurl);
// Set so curl_exec returns the result instead of outputting it.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Get the response and close the channel.
$response = curl_exec($ch);
curl_close($ch);
print($response);

Found the result: with CURLOPT_POST => 1 it works!
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => "https://".$cartodb_key.".cartodb.com/api/v2/sql",
CURLOPT_USERAGENT => 'Sample cURL Request',
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => array(
api_key => $api_key,
q => "INSERT INTO spot (".implode (", ", array_keys($data)).") VALUES (".implode (", ", $data).")"
)
));
$response = curl_exec($ch);
curl_close($ch);
