Hi David,
A "return" statement will immediately halt execution of the current
function and return to where it was called.
In your case, the foreach loop will execute once and find a return
statement, and thus halting execution of the function and returning only
the first filename.
echo() is simply another function call (except it's a language construct
and not a function) and will not halt execution as "return" does.
What you want to do is something like:
$filenames = array();
foreach ($matches as $filename) {
$filenames[] = $filename;
}
return $filenames; // this is now an array containing all the filenames
But this is rather unneccesary, as $matches already is an array and
contains everything you need. Thus all you have to do is:
return $matches;
Which in turn can be shortened to:
function filename($prefix)
{
return glob('images/property_pics/'. $prefix .'*');
}
Happy Thursday!
Timmy

Hi everyone, I have been playing around with some code the list helped me with
a while back and I'm not grasping the concept between return and echo and the
PHP manual doesn't answer this, unless I'm missing something. There is an
example at the very bottom of PHP's return manual, but it's confusing.
So now I'm left wondering why return will only give me the first result in an
array, but echo will give me all the results of the array. Using stuart's
example he had sent me a while back I've messed around with it and modified it
to better understand it:
function filename($prefix)
{
$matches = glob('images/property_pics/'.$prefix.'*');
foreach($matches as $filename){
return $filename;
}
}
echo completeImageFilename($row['MLS_No']);
With the above code I only get the first image of each picture name, but when I
change return to echo, it groups and displays all the pics that have the same
picture name.
