1. I understand what you're doing, and how. But what I don't understand
is why? If a user is going to have to type [B]bold[/B], why not just get
them to type <b>bold</b>. [bold] and [italic] maybe?
2, I think regular expressions are a safer way to go. That way you don't
end up inserting eroneous html into peoples text if an unmatched tag is
encountered. Square brackets will not throw a browser off track but an
unclosed <h1> or <em> tag could ruin a page's appearance.
i suggest using preg_replace, maybe like this:
$pair = array( 'bold' => 'strong',
'italics' => 'em',
'heading1' => 'h1',
'heading2' => 'h2',
'heading3' => 'h3',
'heading4' => 'h4');
$pattern = array();
$replace = array();
foreach($pair as $key => $val) {
$pattern[] = '/(\[)(' . $key . ')(\])([^]].*)(\[\/)(' . $key .
')(\])/i';
$replace[] = "<$val>" . '$4' . "</$val>";
}
$new_body= preg_replace ($pattern, $replace, $body_text);
