Limited uploaded extensions
Hello, I have an upload form for my site where people can upload files for other people to see. I need to limit the extensions, so that people can only upload, for example: .zip files, .swf files, etc. I need to make it so that people can only upload those kinds and not other kinds of files. Can anyone help?

<?php
function file_type_allowed($file)
{
# define allowable file suffixes here (all lower case):
$typesAllowed = array("zip",
"swf",
"txt");
$parts = explode('.', $file);
# if there's a suffix and it's in the list, return true, else false
return((count($parts)<=1) ? FALSE :
in_array(strtolower(array_pop($parts)), $typesAllowed));
}
# test it:
$testData = array("file.txt",
"file.two.Zip",
"file3.SWF",
"file4",
"txt");
foreach($testData as $filename)
{
echo "<p>'$filename' is ";
echo (file_type_allowed($filename)) ? '' : 'not ';
echo "a valid file type.</p>n";
}
?>
