Insert space after comma.
If you have a form that stores results in a database field as comma separated values, when you display this data you can use the following to insert a space after each comma:
<?php
$find[] = ',';
$replace[] = ', ';
$text = str_replace($find, $replace, $row_rsRecordset['Field']);
print_r($text);
?>
Notes:
1) To get round the Replacement Order Gotcha, the comma is also replaced with its code equivalent: ,
2) You can adapt the $replace section to suit your needs: swap out the code with <br/> or replace comma and space with · etc.
