I have written a send sms code which uses an available sms api. So, I need to post a string in the json(string in $json) format to a url(url specified in $url var), but I am getting the following error
String index out of range: -1
I understand that the error arises when requesting for an index that isn't there, but I dont find how that applies in this case. Please help.
Note: name1,name2 and name3 are sender name, phone number and content respectively.
Thanks
array (
'method' = 'POST',
'content' = $data,
'header' ="Authentication:$key" . "timeout:50000"."ContentLength: " . strlen ( $data) . "\r\n"
)
);
if ($optional_headers != null)
{
$params ['http'] ['header'] = $optional_headers;
}
$ctx = stream_context_create ( $params );
try
{
$fp = fopen ( $url, 'rb', false, $ctx );
$response = stream_get_contents ( $fp );
echo "response";
} catch ( Exception $e ) {
echo 'Exception: ' . $e-getMessage ();
echo "caught";
}
echo "done";
return $response;
}
