You can use a browser to upload files with PHP. The files can be either text and binary files. PHP has several file manipulation functions, that allow you to control what you do with a file once it has been uploaded, how large the file to be uploaded should be, where it should go after being uploaded etc.

To upload files, create a file upload form:

Example:

<FORM ENCTYPE="multipart/form-data" ACTION="somephpscript.php3" METHOD=POST>
<INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="1000">
Send this file: <INPUT NAME="userfile" TYPE="file">
