//=======Text to Speech==================
function tts($sentence)

     foreach ($tmp as $value) { 
          $tmp_.= "$value "; 
          $last_word = $value;
          if (strlen($tmp_) > 100) { 
               $last_tmp_.= "";

     foreach ($fragment as &$value)
     {
          $value = str_replace(" ","+",$value);
     }

//     $sentence = str_replace(" ","+",$sentence);
     $name = 0;
     foreach($fragment as $value)
     {
          $url = "https://translate.google.com/translate_tts?tl=en&q=".$value;
          if ($name == 0)
               $fp = fopen("sound/combined.mp3","w");
          else
               $fp = fopen("sound/temp".$name.".mp3","w");
          $ch = curl_init($url);
          curl_setopt($ch, CURLOPT_FILE, $fp);
          $data = curl_exec($ch);
          curl_close($ch);
          fclose($fp);

          file_get_contents($url) or die("oops\n");
          $name++;
     }
     $count = 1;
     while ($count < $name)
     {
          file_put_contents('sound/combined.mp3',
                            file_get_contents('sound/combined.mp3') .
                            file_get_contents('sound/temp'.$count.'.mp3'));
          $count++;
     }
     $count = 1;
     while ($count < $name)
     {
          unlink("sound/temp".$count.".mp3");
          $count++;
     }
}
//=========IN=============
if($tts == 'in'){
tts($alias.'.');
$sound = '<embed src="database/sound/inbeep.mp3" width="0" height="0" ><embed src="database/sound/combined.mp3" width="0" height="0" >';
}

When i run the code I go to the error code "oops" which means it failed to create the file, it was working fine yesterday and i haven't changed anything within the code, i dont know if google is blocking the use of the API or something is wrong with my code.

You need to add the user agent string so you aren't told to be coming from CURL. Your code in the loop should be like this:

$url = "https://translate.google.com/translate_tts?tl=en&q=".$value;
if ($name == 0)
  $fp = fopen("sound/combined.mp3","w");
else
  $fp = fopen("sound/temp".$name.".mp3","w");
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.93 Safari/537.36');
$data = curl_exec($ch);
curl_close($ch);
fclose($fp);
