Hi guys, below are simple script for word replacement, it is replacing a word in to link
$word = array(
'google',
'yahoo'
);
$link = array(
'<a href="http://google.com">google</a>',
'<a href="http://yahoo.com">yahoo</a>'
);
$this->post['message'] = str_ireplace($word, $link, $this->post['message']);
for example text
[QUOTE]i love google result
the output printed will be like this
i love <a href="http://google.com">google</a> result
it is just replacing google text into a link like this <a href=“http://google.com”>google</a>[/QUOTE]
but the problem is if the original google text is already inside a link, like this
<a href="http://google.com">i love google result</a>
the output printed will be broken like this, there will be double hyperlink
<a href="http://google.com">i love <a href="http://google.com">google</a> result</a>
please help guys, how to exclude the text google inside hyperlinks above from replaced, but the text google outside hyperlinks are still replaced
maybe using if statement in the simple script above, or other way
