setlocale() not working properly with date()

Question

I have this piece of code:

<?php

    setlocale(LC_ALL,"es_ES");
    $contador = 1;
    $diaActual = time();

    while ($contador <= 7) {

        echo date("D j-n-Y", $diaActual)."<br><br>";
        $contador++;
        $diaActual = strtotime("+1 day", $diaActual);

    }


?>

Result:

Tue 13-5-2014

Wed 14-5-2014

Thu 15-5-2014

Fri 16-5-2014

Sat 17-5-2014

Sun 18-5-2014

Mon 19-5-2014

Why isn't working?

Answer 1

From the manual about date()

To format dates in other languages, you should use the setlocale() and strftime() functions instead of date().

So use strftime():

print strftime("%a %d-%m-%Y");

To sum up always one day, just use a timestamp like:

for ($time = time(), $contador = 1;
     $contador <= 7;
     $contador++, $time = strtotime('+1 day', $time)) {
    print strftime("%a %d-%m-%Y", $time)."<br />\n";
}
