$GLOBALS
` array to access global variables from anywhere in a PHP script :<?php
// Define a global variable
$global_var = "Hello, world!";
// Define a function that uses the global variable
function print_global_var() {
echo $GLOBALS["global_var"];
}
// Call the function
print_global_var();
?>
Hello, world!
$global_var
` and a function `print_global_var()
` that uses the variable. Inside the function, we use the `$GLOBALS
` array to access the global variable `$global_var
`.$GLOBALS
` array is a special associative array provided by PHP that contains references to all variables that are currently defined in the global scope. This means that you can use the `$GLOBALS
` array to access any global variable from within a function or a class method, without having to pass it as an argument or declare it as a global variable inside the function.
