How to convert "month" to "months", using timestamp in PHP?

[simrah]

Here's the code:

function longadata($data)
{
    if(empty($data)) 
    {
        return "No date provided";
    }
$periods         = array(_segundo, _minuto, _hora, _dia, _semana, _mes, _ano, _decada);
$lengths         = array("60", "60", "24", "7", "4.35", "12", "10");

$now             = time();
$unix_date       = strtotime($data);

if (empty($unix_date)) 
{    
    return "Bad date";
}

if ($now > $unix_date) 
{    
    $difference     = $now - $unix_date;
    $tense          = _atras;   
} 

else 
{
    $difference     = $unix_date - $now;
    $tense          = _agora;
}

for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) 
{
    $difference /= $lengths[$j];
}

$difference = round($difference);

if($difference != 1) 
{
    $periods[$j].= "s";
}

return "$difference $periods[$j] {$tense}";

}

In HTML:

<li class="published-date"><?php echo longadata("2017-08-28") ?></li>

In the result:

3 MÊSS ATRÁS

I want to correct "month" for "months" by code, but I have to keep these codes because of "second", "minute", "year", etc.:

if($difference != 1)

{

$periods[$j].= "s";

}

From what I understand the answer seems to be too obvious, but I don't think that's it, good in any case... In that part I think you just need to put an "e":

if($difference != 1) 
 {
   $periods[$j].= "es";
 }

the exit will be:

3 _meses _atras

I don't know if that was the problem, but if you don't try to explain better that I can help you!
