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"
- Install with composer
composer install victorwesterlund/globalsnapshot
use
in your project
use victorwesterlund\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();
