How would i randomly select a word from the current webpage using php

Hi, i would like to, using php, randomly select a word from the current page, which i have already managed to get into a string.

I would like to use php to randomly choose any of the words, the full word.

 

If you have the words in an array you can do:

$words = array("word1","word2","word3");
$random = rand(0, count($words)-1);
echo $words[$random];

PHP:

To get the words into an array from a string use the explode() function on space characters or something..

 

And you may also need to use array_diff() function to filter out filler words like 'and', 'or', 'be', 'may be', etc. if you need.

 

Thanks, but it dosn't seem to be working for me:

I have made this, using google define:
http://obolynx.com/developments/import.php?word=whom

and i would like to select each word on the page in turn and have it hyperlinked, this is what i have so far codewise:

for($i = 0, $size = sizeof($matches[0]); $i < $size; ++$i) {
     
	  // assuming the string is called "someString"
     $words = explode(" ", $matches[0][$i]);
     $index = rand(0, count($words)-1);
     $choice = $words[$index];
	 $href = '<a href="import.php?word=';
	 $href .= $choice;
	 $href .= '">';
	 $href .= $choice;
	 $href .= '</a>';
	 echo $href;
	 echo $choice;
	 $randomWord = array_rand($words);
	 echo $randomWord;

	}

Code (markup):
