Random Sentences - PHP Snippet Needed

Can somebody post a little php snippet for the following problem?

I have a textfile like this:

I {love|like|need} {coffee|tea}.
He is {cool|nice|awesome} {.|..|!}
Are you {hungry|tired|angry}?

The little php snippet should select one line of the textfile at random and create a random sentence from it, every time i start the php-script.

Example:

After starting the script, it selects line 1: "I {love|like|need} {coffee|tea}."
Then it creates a random sentence like "I like tea." or "I love coffee." (or something like this) from it.

 

You're asking me for an article rewriter right??

 

No it's not really an article rewriter.

The script only writes single sentences.

 

<?php

function rand_wrd($input){
if (!is_array($input)){
return preg_replace_callback('~\{(.+?)\}~', 'rand_wrd', $input);
} else {
$input = explode("|", $input[1]);
return $input[array_rand($input)];
}
}

//the text file containing the sentences....
$file = file('textfilename.txt');

$file = array_map('rand_wrd', $file);

//display a random sentence...
echo $file[array_rand($file)];

?>

For what purpose you need? State that clearly first!
Else it will be a crap for you!
