Question

So in PHP, I am checking a file extension against multiple types to get the general type of file

so here is what I have for images alone:

if ( $ext == "bmp" || $ext == "jpg" || $ext == "png" || $ext == "psd" || $ext =="psp" || $ext == "thm" || $ext == "tif" || $ext == "ai" || $ext == "drw" || $ext == "eps" || $ext == "ps" || $ext == "svg" || $ext == "3dm" || $ext == "dwg" || $ext == "dxf" || $ext == "pln" )

I know that is crazy unefficient, considering the number of if-elses I’ll also need to use. Is there another way of doing this to check files, or maybe a better, premade function (like apaches mime_Magic)? thanks for the help!

To solve just this problem, you can do:

if(in_array($ext, $extensions))

and put those extensions in an array. Be sure you’re checking the actual mimetype of the file, as well, rather than just blindly trusting the extension.
