curl_setopt($tw,CURLOPT_TIMEOUT, 30); // Timeout (for when Twitter is down)
curl_setopt($tw,CURLOPT_RETURNTRANSFER,1); // returns
$json = curl_exec ($tw); // Executes the cURL and puts it into the varible
return $json; // returns what was grabbed
}
function checkandWrite($type){
$cachefile = 'cache/JISCRSCScotNE.'.$type; // the location to your cache file
$cachetime = 10 * 60; // set the cach time 10 * 60 (1 hour)
// if the file exists // if and the time it was created is less then cache time

fwrite($fp, twitterCapture($type)); // writes to the file what was grabbed from the previouse function
fclose($fp); // closes
ob_end_flush(); // finishes and flushes the output buffer
}
