I am brand new to php and have a lot to learn! I'm experimenting with MiniGal Nano for our King County Iris Society website. It work quite well for our purposes with one small exception: the photo file name needs to be visible under the thumbnail. I've created a work around, but it shows the extension. I've found code samples of functions but have no idea how to incorporate them into the existing code. Any assistance would be greatly appreciated.

Many thanks!

Answer: 
You can use `pathinfo()` for that.

```
<?php

// your file
$file = 'image.jpg';

$info = pathinfo($file);

// from PHP 5.2.0 :
$file_name = $info['filename'];

// before PHP 5.2.0 :
// $file_name =  basename($file,'.'.$info['extension']);

echo $file_name; // outputs 'image'

?>

```
If you know for certain that the file extension is always going to be four characters long (e.g. ".jpg"), you can simply use `substr()` where you output the filename:

```
echo substr($filename, 0, -4);

```

If there's a chance that there will be images with more or less characters in the file extension (e.g. ".jpeg"), you will need to find out where the last period is. Since you're outputting the filename from the first character, that period's position can be used to indicate the number of characters you want to display:

```
$period_position = strrpos($filename, ".");
echo substr($filename, 0, $period_position);

```

For information about these functions, check out the PHP manual at <http://php.net/substr> and <http://php.net/strrpos>.
