I have the following array
PHP Code:
$list_day= array('','1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28','29','30','31'); 
and I would like to create a series of variables called $checked

PHP Code:
$checked1 $checked2 $checked3 etc 
I am then placing the $checked# in an input field

PHP Code:
$calendar.= '<div class="day-number">'.$list_day.'<br /><input name="'.$numbers[$list_day].'" type="checkbox" value="x" '.$checked#.' /></div>'; 
I have tried creating the variable like this but it does not work

PHP Code:
$checked = ${'checked' $numerals[$list_day]};
