Simple example of php multi-file Upload

When uploading binary files, remember enctype = "multipart/form-data" Var_dump ($ _ FILES ); ?> Currently, $ _ FILES has only one index, that is After the file is submitted to action. php, the internal structure of $ _ FILES will be as follows: $ _ FILES => array {fileField1 => array 'name' => '*****', 'type' => .......}, fileField2 => array 'name' => '*****', 'type' => .......}, fileField3 => array 'name' => '*****', 'type' => .......}, fileField4 => array 'name' => '*****', 'type' => .......} fileField5 => array 'name' => '*****', 'type' => .......}} The main reason is that the file upload information is changed to multi-dimensional array storage, and relevant information in the file can be obtained just like a single file Upload through a loop.
