php file upload extension checking

you must edit a file manager to only allow upload of certian files, the file manager is [login to view URL] v1.0.1 the upload part is in [login to view URL] i believe (search upload), and all that would be required is a check of the file extension against an array or list of allowed extensions and only upload it if it is allowed it msut be done for the single upload and multi upload (single upload in a loop :)) it would also be preferable for you to not only check the file with php but for you to check it with javascript ie. check if the browse/text field contains .php and give an error. Its not a requirement of the project, but doing it will save server resources as to check with php you need to wait till its uploaded, check the extension and then delete it if its invalid. Please mention wether you can do this or not. Again, it is not a requirement this should be an easy script for someone who has handeled file uploads before, probably not taking more than 15 minutes of their time. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
