using explode

[lucilue2003]

hello,

i have some files that are save like .html or .html.txt
I will be opening these files and i only want to open files that end in .html

i tried this but was unsuceesful.
$testadata1 = ".html.txt";
$test1 = explode(".",$testdata1);
echo $test1;
//output: html

I know there is a better way to do this.

thanks.

scratch head!

surly the output would be

Notice: Undefined variable: testdata1 in blh blah
Array

try

 $testdata1 = ".html.txt"; //corrected spelling error
echo end(explode(".",$testdata1));
