* }

*
|
|
* Optionally, supply an object as the `$bindTo` parameter. This determines
|
|
* the value `$this` will have in the shell, and sets up class scope so that
|
|
* private and protected members are accessible:
|
|
*
|
|
* class Foo {

* function bar() {

|
* \Psy\debug(get_defined_vars(), $this);

|

*
|
|
* For the static equivalent, pass a class name as the `$bindTo` parameter.
|
|
* This makes `self` work in the shell, and sets up static scope so that
|
|
* private and protected static members are accessible:
|
|
*
|
|
* class Foo {
|
|
* static function bar() {
|
|

PsySH is an interactive runtime developer console for PHP. Use it as a REPL
|
|
for quick experiments, or drop into your code with <info>eval(\Psy\sh());</info> or
|
|
<info>\Psy\debug();</info> to inspect application state and debug interactively.
