php-globalsnapshot

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

Supports PHP 8.1+

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

Install with composer

composer install vlw/globalsnapshot

use in your project

use vlw\GlobalSnapshot;

Capture current superglobals with capture()

// Initialize a new GlobalSnapshot instance to store current values (one snapshot per instance)
$snapshot = new GlobalSnapshot();

// Capture current superglobal state
$snapshot->capture();

Restore superglobals with restore()

// ... some other code

// Restore superglobals to state of `capture()`
$snapshot->restore();
