      if(Pagina::delFoto($idDaimagem)){
         if(file_exists('../uploads/photos'.$result['foto'])){

   } ?>

   if($select->rowCount()==1){
      $asfoto = $select(PDO::FETCH_ASSOC);
      $dados['res'] = self::myEvent($asfoto['pagina'],$user_id);

Remove all records from a table with Entity framework 6 Excessive line break when creating C # .txt file?

The problem is that end() expects a reference to be a variable, do the two-step assignment.

Change:

$image = end(explode('-',$_GET['photo']));

To:

$nome = explode('-',$_GET['photo'])
$ext = end($nome);

Watch for signature of functions with & it means that the argument should be passed as reference most of the time.

mixed end (array & array)

Correct @rray's response. The problem is with end accept only variables, not array expressions. Therefore, this function accepts an argument that is a variable, because it is a parameter with reference.

There is a way to circumvent this limitation of the end function.

So:

function last(array $array)
{
    return end($array);
}

In this way, $array , which is a parameter of last , is passed to end as argument, becoming a reference for end , and may be expression for last .

Example:

echo last(explode('-', '1-2-3')); // Imprime '3'
