I would like it to replace any of the .flv .mp4 .webm etc. whit a fixed value of .webm and .flv ..... if file do exist. So a file check is mandatory.
I can't manipulate/add columns to db do to featured upgrades..
a few ex. on filename from db 54b1d96b89943.flv 5547e6f7b2694Politijagtmedover200km_t-[720p].mp4
Can anyone help me out here?

Answer 1

As i understood from your question. You can try this
$fileExtensions=array(original file extensions here);
$replacement=array(replacement extensions);
Then
if(file_exists($fileName)){ str_replace($fileExtensions, $replacement, $fileName);
}

Answer 2

while ( substr($filename,-1)!=".") ){
$filename = substr($filname,0,-1);
}
$filename = substr($filname,0,-1);
$newext=".flv";
$newfilename = $filename.$newext;
