Can we upload file using get method in php?
GET requests may contain an entity bodyRFC 2616 does not prevent an entity body as part of a GET request. This is often misunderstood because PHP muddies the waters with its poorly-named Show Why a GET entity body is a bad ideaSo what does the spec say about the GET method ... well:
So the important thing with GET is to make sure any GET request is safe. Still, the prohibition is only "SHOULD NOT" ... technically HTTP still allows a GET requests to result in an action that isn't strictly based around "retrieval." Of course, from a semantic standpoint using a method named When a GET entity body is flat-out wrongRegarding idempotence, the spec says:
This means that a GET method must not have differing side-effects for multiple requests for the same resource. So, regardless of the entity body present as part of a GET request, the side-effects must always be the same. In layman's terms this means that if you send a GET with an entity body 100 times the server cannot create 100 new resources. Whether sent once or 100 times the request must have the same result. This severely limits the usefulness of the GET method for sending entity bodies. When in doubt, always fall back to the safety/idempotence tests when evaluating the efficacy of a method and its resulting side-effects. This feature lets people upload both text and binary files. With PHP's authentication and file manipulation functions, you have full control over who is allowed to upload and what is to be done with the file once it has been uploaded. PHP is capable of receiving file uploads from any RFC-1867 compliant browser.
PHP also supports PUT-method file uploads as used by Netscape Composer and W3C's Amaya clients. See the PUT Method Support for more details. Example #1 File Upload Form A file upload screen can be built by creating a special form which looks something like this: The The
The global $_FILES will contain all the uploaded file information. Its contents from the example form is as follows. Note that this assumes the use of the file upload name userfile, as used in the example script above. This can be any name. $_FILES['userfile']['name']The original name of the file on the client machine. $_FILES['userfile']['type'] The mime type of the file, if the browser provided this information. An example would be The size, in bytes, of the uploaded file. $_FILES['userfile']['tmp_name']The temporary filename of the file in which the uploaded file was stored on the server. $_FILES['userfile']['error']The error code associated with this file upload. $_FILES['userfile']['full_path']The full path as submitted by the browser. This value does not always contain a real directory structure, and cannot be trusted. Available as of PHP 8.1.0. Files will, by default be stored in the server's default temporary directory, unless another location has been given with the upload_tmp_dir directive in php.ini. The server's default directory can be changed by setting the environment variable TMPDIR in the environment in which PHP runs. Setting it using putenv() from within a PHP script will not work. This environment variable can also be used to make sure that other operations are working on uploaded files, as well. Example #2 Validating file uploads See also the function entries for is_uploaded_file() and move_uploaded_file() for further information. The following example will process the file upload that came from a form.
' The PHP script which receives the uploaded file should implement whatever logic is necessary for determining what should be done with the uploaded file. You can, for example, use the $_FILES['userfile']['size'] variable to throw away any files that are either too small or too big. You could use the $_FILES['userfile']['type'] variable to throw away any files that didn't match a certain type criteria, but use this only as first of a series of checks, because this value is completely under the control of the client and not checked on the PHP side. Also, you could use $_FILES['userfile']['error'] and plan your logic according to the error codes. Whatever the logic, you should either delete the file from the temporary directory or move it elsewhere. If no file is selected for upload in your form, PHP will return $_FILES['userfile']['size'] as 0, and $_FILES['userfile']['tmp_name'] as none. The file will be deleted from the temporary directory at the end of the request if it has not been moved away or renamed. Example #3 Uploading array of files PHP supports HTML array feature even with files.

($_FILES); Can I upload file using GET method?Mainly because GET is used to get information, while POST is used to posting it to the server. Very basically, use GET only for things that do not change anything on the server, and POST only for things that do. Uploading data in a GET command makes perfect sense when the data is a parameter for the GET.
