Get access from an API in PHP - php

Question

im new in PHP, and I have a task to get a data from my client using an API..
but the thing is, can't understand this API even after researching and trying about this..
My client has given me details for the API
URL - http://222.126.31.19:8084/api/login
Username - admin123
Password - test123
those are just a dummy values..
my client also said value should be the token response from login api and prepended by the word "Bearer "
After doing a research.. I tried this codes but nothing appears on my browser.. any idea or suggestion that I can do..
function CallAPI($method, $url, $data = false)
{
$curl = curl_init();
switch ($method)
{
case "POST":
curl_setopt($curl, CURLOPT_POST, 1);
if ($data)
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
break;
case "PUT":
curl_setopt($curl, CURLOPT_PUT, 1);
break;
default:
if ($data)
$url = sprintf("%s?%s", $url, http_build_query($data));
}
// Optional Authentication:
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_USERPWD, "admin123:test123");
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
curl_close($curl);
return $result;
}
Do i need to put this on a button or something? Sorry If I'm asking here, It's been a day and I can't solve it.

Most REST API's are working with some kind of session-id. If you are logging in, you will get an session-id for further calls and a list of possible calls for your login-credentials. But every API is working different. Like BT643 said, they have to give you some form of documentation. I use the following code to access some API's i am using. Try it out, if you like.
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, 'http://222.126.31.19:8084/api/login');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_USERPWD, 'admin123' . ":" . 'test123');
$out = json_decode(curl_exec($ch));
curl_close($ch);
Then you can print out the return-result (if there is any) with:
echo '<pre>'
var_dump($out);
echo '</pre>';
This is just to look if you get any result from your call.
