Capture the current state of all PHP superglobal variables; which can then be restored to that state at a later time.

Example use:

// Initial state
$_ENV["hello"] = "world"; // echo: "world"

// Capture initial state
$snapshot = (new GlobalSnapshot())->capture();

// Manipulate superglobals
$_ENV["hello"] .= " and mom!"; // echo: "world and mom"

// Restore initial state
$snapshot->restore();

// Initial state restored
echo $_ENV["hello"]; // echo: "world"

Quickstart

$snapshot->capture();

1. Restore superglobals with restore()

// ... some other code

// Restore superglobals to state of `capture()`
