Question

I have some numbers which will be part of an sql query, like this…

152258, 152258, 152258, 152258, 152261, 152261, 152261, 152261, 152261, 152270, 
152270, 152270, 152287, 152287, 152287, 152287

My query is quite complex and the list is quite long and I need to produce a unique list of numbers, can I do this with a regex?

If not how ?

Here is how you can make your string have unique numbers:

<?php

$myString = "152258,152258,152258,152258,152261,152261,152261,152261,152261,152270,152270,152270,152287,152287,152287,152287";
$array = explode(",",$myString);
$unique = array_unique ( $array  );
$myUniqueString = implode(",",$unique);
echo $myUniqueString ;
?>
