$msg='Phone:'.$_POST['phone'].',Email:'.$_POST['email'].',Message:'.$_POST['query'].''; // This is dynamic msg.

$response = sentSmS($urlpara);
if($response){

exit;
}else{
header('Location: thankyou.html');
exit;
}
function sentSmS($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
return true;
}

Answer 1

You return $content in sentSmS function, from where you get it? maybe you want to return curl_exec($ch) ?

Answer 2

try debug it:
function sentSmS($url) {
$ch = curl_init();
$options = [
CURLOPT_RETURNTRANSFER => true,
CURLOPT_USERAGENT => 'cUrl',
CURLOPT_CONNECTTIMEOUT => 10, // timeout on connect
CURLOPT_TIMEOUT => 400, // timeout on response - after 400s
CURLOPT_FRESH_CONNECT => true,
CURLOPT_VERBOSE => true,
CURLOPT_URL => $url,
CURLOPT_HEADER => 0
];
curl_setopt_array( $ch, $options);
$result = curl_exec($ch);
if (empty($result)){
$error = curl_error($ch);
$errorNumber = curl_errno($ch);
$exception = new \Exception('curl call error: '.$error, $errorNumber);
throw $exception;
}
curl_close($ch);
return $result;
}
