What are some best practices for using "=" and "->" in PHP code to avoid errors or misunderstandings?

When writing PHP code, it's important to use "=" for assignment and "->" for accessing object properties or methods. Mixing up these operators can lead to errors or misunderstandings in your code. To avoid this, always double-check your usage of "=" and "->" to ensure they are used correctly. Example: ``` // Incorrect usage of "=" and "->" $variable->property = "value"; // This will result in an error // Corrected usage of "=" and "->" $object->property = "value"; // Assigning a value to an object property $object->method(); // Calling a method on an object ```
