How to change this PHP 5.3 code to PHP 5.4?

Question

How can I change the code below to work in PHP versions 5.3 and 5.4? It currently only works in version 5.3.

I’m having the following mistake:

Strict Standards: Only variables should be passed by Ference in /home/public_html/admin/additor.php on line 1

$arquivo_renomeado = strtolower(end(explode('.', $nome_do_arquivo_original_alterado)));
if ($arquivo_renomeado == 'jpg' || $arquivo_renomeado == 'jpeg') {
    $nome_final = str_replace($nome_do_arquivo_original_alterado,' ',$nome_da_imagem_alterada.'.jpg');
} else if ($arquivo_renomeado == 'png') {
    $nome_final = str_replace($nome_do_arquivo_original_alterado,' ',$nome_da_imagem_alterada.'.png');
# Only if your version of GD includes GIF support
} else if ($arquivo_renomeado == 'gif') {
    $nome_final = str_replace($nome_do_arquivo_original_alterado,' ',$nome_da_imagem_alterada.'.gif');
}

Answer 1

The error says that you are required to pass a variable(reference) to end function, it is not possible to pass the return of a function/method. To fix create an intermediary variable that takes the array of explode(), then pass her on to end().

Stay tuned to look at the php manual most of the functions you have &(commercial) indicate that the parameter must be a variable and not a value or function return.

Mixed end ( array &$array )

The code should stay that way:

$nome_do_arquivo_original_alterado = 'teste.png';
$arr = explode('.', $nome_do_arquivo_original_alterado);
$arquivo_renomeado = strtolower(end($arr));

Complementing the gmsantos commentary, from php5.3 E_STRICT does not belong to E_ALL. Already in php5.4 E_STRICT became part of E_ALL. To display errors/warnings E_STRICT in php5.3 add these two lines at the beginning of the script:

 ini_set('display_errors', true);
 error_reporting(E_ALL | E_STRICT);
