Adding a link to each word in a string

[jamiet757]

I have been becoming more and more familiar with PHP over the past few months, but this problem stumps me.

 

How can I take a string of words separated by spaces taken from an XML feed (example: word1 word2 word3 word4)

 

and turn it into something like this:

 

<a href="word1">word1</a>

<a href="word2">word2</a>

...

 

and so on. This has to be done on the fly, since it is taking the words from the XML feed, they change depending on the page.

 

I want them to be in a vertical column, and be able to link each one to the search page for that word, so each link has to be different.

 

 

An even more in-depth problem, how can I sort it then so that there are multiple columns if necessary, say one page only has 3 words, but another has 50. How can I split them up into multiple vertical columns, say with 10 words in each?

 

 

Have I confused anyone yet?

[premiso]

$string = "word word word";

$array = explode(" ", $string);

$display = "";
foreach ($array as $word) {
    $display .= '<a href="' . $word . '">' . $word . '</a>';
}

echo $display;

 

Should do it for ya.

wow, thanks! I am amazed at how easy that was, I should have been able to come up with it!

 

How about seperating them into multiple columns, so in case I have a string with 100 words I don't have a huge page of links?
