Question

I’ve been trying using array_map to convert characters to HTML entities with htmlentities() like this:

$lang = array_map('htmlentities', $lang);

My array looks like this:

$lang = array();
$lang['var_char1']['varchar2'] = 'Some Text';

But I keep getting this errors:

Warning: htmlentities() expects parameter 1 to be string, array given
in /home/user/public_html/foo/lang/en.inc.php on line 1335

Does anyone know what could be the problem? Thank you!

Answer 1

Because $lang is a two dimensional array, so it won’t work

For two dimensional array you need to use for loop

foreach($$lang as &$l):
    $l = array_map('htmlentities', $l);
}
