Copy code 如 Code as follows: Function Cleanglobal ($ Global_array, $ Arg, $ Specialchars = True, $ Default = NULL) {
(key_exists ($ ARG, $ GLOBAL_ARRA y) && $ global_array [$ arg ] != null && $global_array[$arg] != "") { else {
return $global_array[$arg];
}
} else {
return $default;
The above introduces the code of global variables php to obtain global variables, including the content of global variables. I hope it will be helpful to friends who are interested in PHP tutorials.
