PHP Spinning Syntax

At the minute I am able to spin articles but I have to create a list of arrays for certain words and then echo a random word from the array to give a spun effect.

How would I go about in PHP making it so that if I just put in the following it would spin the text?

"I wear a {yellow|green|blue} {coat|jacket|T shirt}"

I have looked on the net but can't seem to find anything.

 

<?php
$input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");

function randomWord($input){
shuffle($input);
return $input[0];
}

echo "My matrix hero is ". randomWord($input);

?>

PHP:

 

More specific.....

<?php
$colour = array("yellow", "green", "blue");
$item = array("coat", "jacket", "t-shirt");

function randomWord($input){
shuffle($input);
return $input[0];
}

echo "I wear a ". randomWord($colour) . " " . randomWord($item);

?>

Few months ago I did the same thing

 

Thanks for the reply, I can do it with that but how to I make it so I can just use the universal spinning syntax so that when something is within the tags it puts it into arrays?

 

<?php


$text = 'I wear a {yellow|green|blue} {coat|jacket|T shirt}.
My mother is very {nice|mad} to me. I wish I could do things as that { but why.
I like doing things that do not make sense}. {}';


preg_match_all('/\{(.*[|].*)\}/Uis',$text,$result);

foreach($result[1] as $curItem)
{
	$curArray = explode('|',$curItem);
	$curItem = '{'.$curItem.'}';
	$arrayCount = count($curArray);
	$text = str_replace($curItem,$curArray[rand(0,$arrayCount-1)],$text);
}

echo $text;
?>

PHP:

This should do it.
