make php variable from plain text get file

Question

currently i am using the below code to get a file from a site which tells me the current server status of a game server. the file is in plain text format and out puts the following depending on server status:

ouput:

{ "state": "online", "numonline": "185" }

or

{ "state": "offline" }

or

{ "state": "error" }

file get code:

<?php 
   $value=file_get_contents('http:/example.com/server_state.aspx');
      echo $value;
?>

I would like to turn the 'state' and 'numonline' into their own variables so i could output them using a if, like:

<?php 
$content=file_get_contents('http://example.com/server_state.aspx');

$state  <--- what i dont know how to make
$online <--- what i dont know how to make

if ($state == online) {     
   echo "Server: $state , Online: $online"; 
}  else {
   echo "Server: Offline";
)       

?>

but i have no idea how to turn the 'state' and 'numonline' from the plain text into a variable of their own ($state and $online), how would i go about doing this?

It's not plain text format, it's json. Use json_decode() php.net/manual/de/function.json-decode.php on the string you get the contents of — thpl

Your data is JSON. Use json_decode to parse it into a usable form:

$data = json_decode(file_get_contents('http:/example.com/server_state.aspx'));

if (!$data) {
    die("Something went wrong when reading or parsing the data");
}

switch ($data->state) {
    case 'online':
        // e.g. echo $data->numonline
    case 'offline':
        // ...
}

Use json_decode function:

$value = '{ "state": "online", "numonline": "185" }';
$json = json_decode($value, true);
print_r($json);

if ($json['state'] == 'online') {     
   echo "Server: " . $json['state'] . " , Online: " . $json['numonline']; 
}  else {
   echo "Server: Offline";
}

Output:

Array
(
    [state] => online
    [numonline] => 185
)
