Let's try another example, based on your code:
Example 1: using return
=======================
function completeImageFilename($prefix) //correcting function name
{
$matches = glob('images/property_pics/'.$prefix.'*');
foreach($matches as $filename){
return $filename;
}
}
echo "This is the complete image file name:
".completeImageFilename($row['MLS_No']) . PHP_EOL;
You will get one line of output with the text from the echo statement
and the first filename that matches.
Example 2: using echo
=====================
function completeImageFilename($prefix) //correcting function name
{
$matches = glob('images/property_pics/'.$prefix.'*');
foreach($matches as $filename){
echo "This is the file name from inside completeImageFilename: " .
$filename . PHP_EOL;
}
}
echo "This is the complete image file name:
".completeImageFilename($row['MLS_No']) . PHP_EOL;
You will get several lines of output for each filename that matches
with the text from the echo statement inside the function, then one
more line that will contain *just* the text from the final echo
statement:
This is the file name from inside completeImageFilename:
images/property_pics/151136.jpg
This is the file name from inside completeImageFilename:
images/property_pics/151137.jpg
This is the file name from inside completeImageFilename:
images/property_pics/151138.jpg
This is the file name from inside completeImageFilename:
images/property_pics/151139.jpg
This is the complete image file name:
(the file names are bogus and just made up by me to illustrate)
