php - Mail() only sending first word from subject

When i send some email, it only sends the first word from the subject:

Example: I send an email with the name of "Send email", it only sends the word "Send", how can i prevent that?

Code:

The subject is selected in a select box

  foreach($templatesarr as $val){

   echo ''.$val['name'].'';
  }
  echo '
  
  
  ';
  ?>
  

Check if the button was clicked

if(isset($_POST['send'])){
$sendername = 'Company';
$from = 'noreplay@compaty.com';
$to      = safe($_POST['to']);

$subject =  safe($_POST['subject']);
$message = 'teste';


$headers  = 'MIME-Version: 1.0' . PHP_EOL;
$headers .= 'Content-type: text/html; charset=iso-8859-1' . PHP_EOL;
$headers .= "From: $sendername <$from>".PHP_EOL;

mail($to, $subject, $message, $headers);

}else{
$to = NULL;

}

Safe function

function safe($value) {
    return mysql_real_escape_string($value);
}

Answer

The main problem is caused by not escaping variables and not properly encapsulating your attribute values; use this instead:

foreach($templatesarr as $val){
   printf('%1$s', 
       htmlspecialchars($val['name'], ENT_QUOTES, 'UTF-8')
   );
}

It now uses "" to delimit the value attribute of the option element.
