Besides the already posted solutions to your problem, here two more
suggestions:

1. preg_replace can also work with pattern/replacement arrays:

$patterns = array(
'/</',
'/>/',
'/@/',
"/(http:\/\/[^\s]+)/"
);

$replacements = array(
'<',
'>',
'_at_',
"<a href=\"$1\">$1</a>"
);

$hyprtext = preg_replace($patterns, $replacements, $textline);

2. Except the last pattern, the other three could also easily be done
with a "simple" str_replace:
