Question

How do I output a formatted text using php. I’m storing it in a field will longtext data type. I save the data using the code below:

<?php 
if(!empty($_POST)){
    $code = mysql_real_escape_string($_POST['x']);
    $db->query("INSERT INTO tbl_codes SET code='$code'");
}
?>

But when I try to retrieve it:

<?php echo htmlentities($yo); ?>

It’s not already formatted. And if I don’t use the htmlentities function, I don’t see any output. Please help

As the doc says, htmlentities will convert chars like ‘<‘ and ‘>‘ in ‘<‘ and ‘>‘ thus the html tags will have no effect. For example, if you have bolded text like this:

<b>example</b>

it will be converted in:

<b>example</b>

Since in your last comment you write that you only need the <pre> tag, you can consider the possibility to use strip_tags like:

$cleanOutput = strip_tags($yo, '<pre>');
