I have created a function
that grab the title
from the given URL and return json
. The function is call by ajax
. All works fine but when any title contain the ü or any related character it return null
. I have echo the string in Network tab it shows � instead of character's like ü.
I have tried the solution I get from the internet like to use JSON Constant
, solution[1] , solution[2], solution[3] and many
After I tried htmlentities
but it return null string
Code:
$value = array();
$val['title'] = get_title("URL");
$val['link'] = $line;
array_push($value, $val);
function get_title($url)
{
$curl_handle = curl_init();
curl_setopt($curl_handle, CURLOPT_URL, $url);
curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
$query = curl_exec($curl_handle);
curl_close($curl_handle);
$normalizeChars = array(
