Incomplete week name on strftime return

Question

I am trying to print the day of the week, according to a certain timestamp, with the function strftime.

I’m doing it this way:

setlocale(LC_ALL, 'pt_BR', 'pt_BR.iso-8859-1', 'pt_BR.utf-8', 'portuguese');

echo strftime('%A', strtotime('now'));

I expected the result quinta-feira, but I am returned quinta.

Why did this happen? The result should not be quinta-feira?

I am using the Ubuntu, with the PHP 5.5.9-1 ubuntu 4.11

I’m using Laravel 4 and this problem occurs in the object Carbon\Carbon.

Example:

#filters.php
App::before(function ()
{
     setlocale(LC_ALL, 'pt_BR', 'pt_BR.iso-8859-1', 'pt_BR.utf-8', 'portuguese');
});

#view qualquer
$usuario->created_at->formatLocalized('%A'); // quinta

Observing: I don’t want to wear one array with the list of all days of the week (thank you)

Answer 1

PHP removes locale information from the operating system it is running on. As described in the documentation:

Note: The setlocale() return value depends on the system on which the PHP is running. It returns exactly what the function setlocale of the system returns.

So if the operating system displays the days of the week without the "-fair" the dates displayed by the locale will be like this.

Using your own example:

<?php
//teste.php

setlocale(LC_ALL, 'pt_BR', 'pt_BR.iso-8859-1', 'pt_BR.utf-8', 'portuguese');
echo strftime('%A', strtotime('now'));
echo PHP_EOL;

When I run this script:

adirkuhn: ~ $ php teste.php 
quinta

---

Okay, so compare it to my operating system. First in the current locale (English):

adirkuhn: ~ $ date +%A
Thursday

And now with the pt_BR locale:

adirkuhn: ~ $ LC_TIME=pt_BR.UTF8 date +%A
quinta

---

So you have two options or add the "-fair" in hand with PHP even though it is easier.

Or changes the operating system locale file. My test with the modified locale:

...
LC_TIME
abday   "<U0044><U006F><U006D>";"<U0053><U0065><U0067>";/
        "<U0054><U0065><U0072>";"<U0051><U0075><U0061>";/
        "<U0051><U0075><U0069>";"<U0053><U0065><U0078>";/
        "<U0053><U00E1><U0062>"
day     "<U0064><U006F><U006D><U0069><U006E><U0067><U006F>";/
        "<U0073><U0065><U0067><U0075><U006E><U0064><U0061><U002D><U0066><U0065><U0069><U0072><U0061>";/
        "<U0074><U0065><U0072><U00E7><U0061><U002D><U0066><U0065><U0069><U0072><U0061>";/
        "<U0071><U0075><U0061><U0072><U0074><U0061><U002D><U0066><U0065><U0069><U0072><U0061>";/
        "<U0071><U0075><U0069><U006E><U0074><U0061><U002D><U0066><U0065><U0069><U0072><U0061>";/
        "<U0073><U0065><U0078><U0074><U0061><U002D><U0066><U0065><U0069><U0072><U0061>";/
        "<U0073><U00E1><U0062><U0061><U0064><U006F>"
...

Date testing by the system:

adirkuhn: ~ $ LC_TIME=pt_BR date +%A                                                                                  
quinta-feira

And now the PHP test:

adirkuhn: ~ $ php teste.php                                                                                           
quinta-feira

Answer 2

With dates to always several possible solutions. Here are some:

$diasSemana = array('domingo', 'segunda-feira', 'terça-feira', ...);
echo $diasSemana[strftime('%w', strtotime('now')];

---

$now = strtotime('now');
echo strftime('%A', $now);

$decimalDiaSemana = strftime('%w', $now);
if ($decimalDiaSemana > 0 && $decimalDiaSemana < 6) {
    echo '-feira';
}

---

$now = strtotime('now');
$sufixo = array('', '-feira', '-feira', '-feira', '-feira', '-feira', '');
echo strftime('%A', $now) . $sufixo[strftime('%w', $now);
