Hi guys, below are simple script for word replacement, it is replacing a word in to link

PHP Code:

$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

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>

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

Maybe you can use strip_tags to remove all a tags from message and then insert your own tags.

There's an example on the page cited. Furthermore, if you can't knock up a two line script to test it you shouldn't be writing code - have a go, ffs.

I don't know nothing about OOP but I can try.

PHP Code:

$word = array(
'google',
'yahoo'
);

$link = array(
'<a href="http://google.com">google</a>',
'<a href="http://yahoo.com">yahoo</a>'
);

$this->post['message'] =  strip_tags($this->post['message']); 
$this->post['message'] = str_ireplace($word, $link, $this->post['message']); 


Try using preg_replace(). It's a combination of the replace function and regular expressions. Which means, you can use regual expressions to just match the exact word "google", and not just anything containing the word.

You can look more into regular expressions if you're interested, but I think this should do it.

PHP Code:

$search = array("/^google$/i", "/^yahoo$/i");
$replace = array('<a href="http://www.google.com">google</a>', '<a href="http://www.yahoo.com">yahoo</a>');

$this->post['message'] = preg_replace($search, $replace, $this->post['message']);
