Array list problem

[ironman32]

I have an array list which currently puts out data at random. What I would like is for it to output random data in an ordered list but not to have the same data appear more than once on the list

here is the code

 

<?php
srand((float) microtime() * 1000);
$input2 = array("<a href =\"http://www.muscleandstrength.com/exercises/barbell-bench-press.html\">Bench press</a>", 
"<a href =\"http://www.muscleandstrength.com/exercises/military-press-behind-neck.html\">Military Press behind the neck</a>", 
"<a href=\"http://www.liverpoolfc.tv\">A</a>","<a href =\"http://www.muscleandstrength.com/exercises/military-press-behind-neck.html\">C</a>",
"<a href =\"http://www.muscleandstrength.com/exercises/military-press-behind-neck.html\">B</a>",);

$rand_keys2 = array_rand($input1, 3);


?>

 

Here is the ordered list

<ol>
<li>Stretch/Warm up </li><br></br>
<li><?php echo $input2[$rand_keys[1]] . "\n"; ?></li>
<li><?php echo $input2[$rand_keys[2]] . "\n"; ?></li>
<li><?php echo $input2[$rand_keys[1]] . "\n"; ?></li>
<li><?php echo $input2[$rand_keys[2]] . "\n"; ?></li>
</ol>

 

Any help would be appreciated

you could try and use if (!in_array()) { add to array }
