I wanted to make a PHP function that would make text bold between double asterisks, and italic between one asterisk, (quite like the editor on Stack Overflow).
The same rules apply, if there's a space between the * and the word, it shouldn't render.
I tried, but I only came this far, as I don't know how to make the odd asterisks <b>
and the even ones </b>
:
$thenewtext = str_replace("**", "<b>", "**Hello World** of PHP");
A simple regex will do the trick:
$thenewtext = preg_replace('#\*{2}(.*?)\*{2}#', '<b>$1</b>', '**Hello World** of PHP');
