How to pass decoded HTML strings to JS?

hi i have created a php file for users to comment in my website this is the line

 $comment  = $get_row[2];
$jsonarray = array('User' => $get_row[1],'Comments' => $comment, 'Post' => $get_row[3],'Date' => $get_row[4]开发者_开发技巧,'Like' => $get_row[5],'Dislike'=>$get_row[6],'islike' => $is_like,'abuse' => $get_row[7]);

but in comment box when i enter " " " it showing like

""&quot;

is there any function in php to decode this string and it show as a original user entered string like " " "

<?
$x = '"with quotes" &quot;';

print htmlspecialchars_decode($x);
?>
