Restrict file types in upload

[FullyH3ktik]

Hey does anybody know how to restrict the file type .exe from uploading?

thanks in advance

You could use the function eregi.

Like so:
[PHP]
[PHP]if (eregi (.exe*)){
//.exe file exists
}else{
//.exe. doesn't exist
}
[/PHP]

Could you perhaps write a "mini script" to show me how you would incorporate that into the file upload
Much appreciated.

Here is a snippet to restrict file type uploads:

$allowedExtensions = array("txt","csv","htm","html","xml","css","doc","xls","rtf","ppt","pdf","swf","flv","avi","wmv","mov","jpg","jpeg","gif","png");
    foreach ($_FILES as $file) {
        if ($file['tmp_name'] > '') {
            if (!in_array(end(explode(".",strtolower($file['name']))),$allowedExtensions)) {
                die($file['name'].' is an invalid file type!<br/>'.'<a href="javascript:history.go(-1);">'.'&lt;&lt Go Back</a>');
            }
        }
    }
