What is the significance of using $this in object context in PHP, and what potential issues can arise when using it outside of object context?

Using `$this` in object context in PHP refers to accessing properties and methods of an object within a class. When used outside of object context, such as in a static method or a global function, PHP will throw an error. To solve this issue, you can either pass the object as a parameter to the function or method, or use the `self` keyword to access static properties and methods within the same class. 

class MyClass {
    public $property = 'value';
    
    public function myMethod() {
        myFunction($this); // Pass $this as a parameter
    }
}

function myFunction($object) {
    echo $object->property;
}
