Hello all: Thanks for just being here.... I had a very vexing problem and in composing the text of the question I hit on the answer to the problem an the solution. It involves the html form attribute enctype="multipart/form-data" used for uploading files to the server, and the $_FILES superglobal. It appears that php creates the $_FILES global when it sees this enctype header in a post request, whether or not there are files to be uploaded.

Are you asking why it is doing it?

No, not exactly, as a matter of fact I am not asking anything at this point. I determined, tentatively what I need to know to solve a problem with post request from html page that contained an enctype attribute with value multipart/form-data for uploading files. The problem occurs when another set of form elements in the same form element, not concerned with file uploads, was being submitted, with the enctype and MAX_FILE_SIZE hidden field still present. The solution is to revise the javascript used for form submission. It can add the enctype attribute and fill out the hidden field at the last step before calling submit() to actually upload the file. In this way all the other form configurations ( four different configurations including the uploading facility) will definitely not have these elements present when they are submitted. I had this conditional in the php side: if($_FILES && POST) { // supposed to just process uploads // but this code is being run when other // parts of the form that don't upload files // are submitted: most likely because the enctype attribute // and the MAX_FILE_SIZE hidden fields are presented. } JK
