I have a file that is being uploaded, but I need to remove all the characters
in the filename except letters, numbers, and the '.' (dot). Example would be
'where_i_go.mp3' removing the '_' to get 'whereigo.mp3'. Below is what I have
to remove the none letters and numbers, but it also takes away the '.' (dot).
How can I make the code below keep the dot?
$filename = ereg_replace("[^a-zA-Z0-9]", "",$filename);
Regards,
Joseph A. Bannon
