Use functions to delete and copy files. check whether magic reference is enabled.

The deletion and copying of files through functions has shown whether magic reference is enabled. /** I still have a hard time * The custom addslashes function supports multi-dimensional arrays and automatically identifies whether the server enables magic reference. */ Function add_slashes ($ var ){ // First determine whether the server supports magic reference If (get_magic_quotes_gpc () = 0 ){ If (is_array ($ var )){ // Traverse the array Foreach ($ var as $ key => $ value ){ $ Var [$ key] = add_slashes ($ value ); } Return $ var; } } Elseif (is_string ($ var )){ // It is a string instead of an array. Return addslashes ($ var ); } Else { // Enabled Return $ var; } } // Copy function to copy files and folders Function dir_copy ($ src, $ dst ){ If (is_dir ($ src )){ If (! File_exists ($ dst )){ @ Mkdir ($ dst, 0777, true ); } } $ Fp = opendir ($ src ); While (! False = ($ fn = readdir ($ fp ))){ If ($ fn = "." | $ fn = ".."){ Continue; } $ Path = $ src.
