Translate month - php

Question

I'm currenty looking into this tutorial to create a calendar. The only problem I have atm is that my months are in english instead of dutch. How can I change the output of 'july' to 'juli' ?
<?php
$vandaag = date("d"); // Current day
$maand = date("m"); // Current month
$jaar = date("Y"); // Current year
$dagen = cal_days_in_month(CAL_GREGORIAN,$maand,$jaar); // Days in current month
$vorigemaand = date("t", mktime(0,0,0,$maand-1,1,$jaar)); // Days in previous month
$begin = date("N", mktime(0,0,0,$maand,1,$jaar)); // Starting day of current month
$einde = date("N", mktime(0,0,0,$maand,$dagen,$jaar)); // Finishing day of current month
$vorigestart = $begin - 1; // Days of previous month in calander
$counter = 1;
$volgendeMaandCounter = 1;
if($begin > 5){ $rows = 6; }else {$rows = 5; }
for($i = 1; $i <= $rows; $i++){
echo '<tr class="week">';
for($x = 1; $x <= 7; $x++){
if(($counter - $begin) < 0){
$date = (($vorigemaand - $vorigestart) + $counter);
$class = 'class="blur"';
}else if(($counter - $begin) >= $dagen){
$date = ($volgendeMaandCounter);
$volgendeMaandCounter++;
$class = 'class="blur"';
}else {
$date = ($counter - $begin + 1);
if($vandaag == $counter - $begin + 1){
$class = 'class="today"';
}
}
echo '<td '.$class.'><a class="date">'. $date . '</a></td>';
$counter++;
$class = '';
}
echo '</tr>';
}
?>
Thanks in advance!

try with this code:
setlocale(LC_TIME, 'de_DE', 'deu_deu');
/* print test date string */
echo strftime("%A, %d. %B %Y");
