BB code function not working

[SirChick]

I have this function that is suppose to show fonts in bold etc using html but it just shows it as like normal:

 

<b>tst</b>

^thats how it shows rather than : tst

 

 

This is my function:

 

function bbcode_format($Notes){
$Notes = htmlentities($Notes);
$simple_search = array(
                                '/\[b\](.*?)\[\/b\]/is'
                                );

        $simple_replace = array(
                                '<strong>$1</strong>'
                                );

        // Do simple BBCode's
        $Notes = preg_replace ($simple_search, $simple_replace, $Notes);

        echo $Notes;
}

try this :

 

$words = array('[b]','[/b]');		
$code = array('<strong>','</strong>');

$Notes= str_replace($words, $code, $Notes);

function bbcode_format($Notes){
$Notes = htmlentities($Notes);
$simple_search = array(
                                '/\[b\](.*?)\[\/b\]/is'
                                );

        $words = array('[b]','[/b]');		
$code = array('<strong>','</strong>');

$Notes= str_replace($words, $code, $Notes);
