This article will explain in detail how PHP uploads the file code for you. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The two main functions are move_uploade_file (temporary file, target location and file name) and is_uploaded_file (), the former is used to move the file saved in the server cache to the target file after upload, and the latter is used to determine whether the file is uploaded successfully. In addition to the above two functions, it is important to note that the value of enctype in the form tag should be as follows:

Only a value of multipart/form-data can guarantee that the file is uploaded in the correct encoding. "file" in the type attribute of the input tag

Another system function is the original name of the $_ FILES,$_FILES ['myFile'] [' name'] client file, the MIME type of the $_ FILES ['myFile'] [' type'] file, such as "image/gif", $_ FILES ['myFile'] [' size'] the size of the uploaded file, in bytes, the temporary file name stored in $_ FILES ['myFile'] [' tmp_name'] Generally speaking, the system defaults to $_ FILES ['myFile'] [' error'] the error code related to the upload of this file. This function splits the information of the uploaded file into arrays and stores it in different array elements, for example, the value of the file name is stored in $_ FILES ['myFile'] [' name'].
