Hi, I'm a newbie to PHP, but I'm learning (I love it allready 8) )...

I wanted to build a script that checks a directory for certain JPG buttons. Is it possible to make the script to look if (for example) the JPG button is present, if not the JPG story turns into a story of tables?

you can use the file_exists(filename) function. it takes a file name as an argument and returns true if it finds it, or false if it doesn't.

Thx!

Now there's one problem left, I need to filter a string down to the last dot ( . ), then remove everything behind the dot and replace it with JPG

Code: Select all

$a = explode(".", $string);
$a[sizeof($a)-1] = "jpg";
$file = implode(".", $a);
makes an array $a, fills it with the pieces of the string that are seperated by a period then replaces last element of the array (whatever came after the last period) with jpg. finally rebuilds the string as $file seperating each element of the array by a period.
