In PHP, objects are complex data structures that can contain multiple properties and methods. Converting an entire object to a string without any specific instructions could lead to a loss of information and ambiguity .
To handle object-to-string conversion in a controlled and predictable manner, PHP provides the __toString() method. By implementing this method within a class, you can define how the object should be represented as a string. This allows you to have explicit control over the string representation of the object.
However, if a class does not implement the __toString() method or the method is not accessible (e.g., private or protected), PHP does not have a default way to convert the object to a string. In such cases, attempting to directly convert the object to a string will result in a fatal error.
