Uh Oh, we're in trouble ;-)
Sorry about that Jim, I accidently typed the wrong function name. Here's the
corrected code. Everybody's answer was spot on and I learned a great deal
about return and echo. :-)
function completeImageFilename($prefix)
{
$matches = glob('images/property_pics/'.$prefix.'*');
foreach($matches as $filename){
return $filename;
}
}
echo completeImageFilename($row['MLS_No']);
