How can the use of custom exceptions in PHP classes enhance error handling and code readability, as discussed in the forum thread?

Using custom exceptions in PHP classes can enhance error handling by allowing developers to create specific exception classes for different types of errors, making it easier to identify and handle them appropriately. This can also improve code readability by clearly indicating the cause of an error and providing more context to the developer. By throwing custom exceptions in classes, the code becomes more organized and maintainable. 

<?php

class CustomException extends Exception {}

class MyClass {
    public function doSomething($value) {
        if ($value < 0) {
            throw new CustomException("Value cannot be negative");
        }
        // Other operations
    }
}

try {
    $obj = new MyClass();
    $obj->doSomething(-5);
} catch (CustomException $e) {
    echo "Error: " . $e->getMessage();
}

?>
