This should do what you want. You'd have to change the names of the months to the language of your choice of course.
I hope this makes sense to you. Please email me with any questions.
<?php
//Creates an array of months. Starts the index at 1 instead of 0 for compatibility with getdate()
$month = array ('1' => 'January','February','March','April','May','June','July','August','September','October','November','December');
//Assigns the date to a variable.
$today = getdate();
//$today['mon'] is the current month in numeric form.
//$month[$today['mon']] pulls out the value from the $month array corresponding to an index of the current month.
echo $month[$today['mon']];
?>
