Replace numbers

Question

In a select I search for names and products.
The products-field in the database is a varchar type, in
which numbers
from 1-7 (comma separated) are stored (not the best design,
yes).
My repeat region is:
<?php do { ?>
<?php echo htmlentities($row_rsClient['name']);
?><br />
<?php echo $row_rsClient['products']; ?>
<?php } while ($row_rsClient =
mysql_fetch_assoc($rsClient)); ?>
That displays these results:
A 1,3,4
B 2 and so on.
I would now like to replace the "1" by "A", the "2" bei "B"
and so on.
An example I tried is:
$output=str_replace("1", "A", $row_rsClient['products']);
How could that be integrated into a repeat region behavior?
And how
could I replace all the numbers (1-7) by the products in one
go?
Thank you.

preg_replace() can take arrays as arguments, so you can do
everything
in one pass:
http://www.php.net/preg_replace
In your case, you'd do something like:
<?php
$patterns = array("1", "2", "3");
$replacements = array("A", "B", "C");
?>
<?php do { ?>
<?php echo htmlentities($row_rsClient['name']);
?><br />
<?php
output = preg_replace($patterns, $replacements,
$row_rsClient['products']);
echo $output;
?>
<?php } while ($row_rsClient =
mysql_fetch_assoc($rsClient)); ?>
