Well, the string concatenation can be used to force PHP read and print a variable within a echoed or printed string. As far as I know, it should be used to make PHP handle a function inside a string. i.e.
echo "your total is:". total_function(); In your example, you might use as well: echo "<img src=\"../site/products/" . $prod_sku.gif . "\"; having the same results. Notice how the HTML part is always enclosed by quotes. PHP server reads this as: echo "<img src=\"../site/products/whatever.gif\"; Hope this works, C. > -----Original Message----- > From: Jen Swofford [mailto:[EMAIL PROTECTED]] > Sent: Sunday, July 07, 2002 2:31 PM > To: [EMAIL PROTECTED] > Subject: [PHP-DB] concatenating (was: RE: [PHP-DB] Retrieving/Displaying > hyperlinked images with PHP) > > Can somebody explain to me the rule on concatenating?
