transform string

As transform this string 
"house, place, free," 
in this 
"<a href="url=house">house</a> <a href="url=place">place</a>" <a href="url=free">free</a>"

<?php
// Your string of words
$str = "house, place, free,";
// Separate them at the commas, into an array
$str = explode(',', $str);
// Set the $html variable so we can add to it with the following foreach
$html = '';

foreach($str as $val)
{
        // EDIT: Trim $val so spaces don't matter
$val = trim($val);
$html .= '<a href="url='.$val.'">'.$val.'</a> ';
}

echo $html;
?>

 

And you can add to that string as much as you want, as long as the words are separated by commas.

Comma and spaces, actually.  I'd probably use:

 

$str = split(',[ ]*', $str);

 

That way if you forget a space, it'll still work.  Also, why do you have href="url=something"?  That makes little sense.

gonna assume it's used as a controller or switch

Let's say you were on http://www.example.com/index.php.  A link formatted as such:

 

<a href="url=house">house</a>

 

Would then lead you to:

http://www.example.com/url=house

 

So I think he needs to fix that. =P

I was under the impression that he was just going to replace 'url' with his actual URL once he got the code...

No need to use regex here, not complex enough... explode and trim will be quite a bit quicker.

[DarkWater]

Okay, fair enough, then he just needs to change the explode to:

 

explode(',', $str);

 

And leave out the trailing space.
