What is the significance of passing the full path to a class in a specific namespace when using class_exists() in PHP?

When using `class_exists()` in PHP, it is important to pass the full path to a class in a specific namespace to ensure that the function can correctly determine if the class exists. This is necessary because classes with the same name can exist in different namespaces, and specifying the full path helps to avoid conflicts and ambiguity. 

// Example of passing the full path to a class in a specific namespace when using class_exists()
if (class_exists('Namespace\ClassName')) {
    // Class exists in the specified namespace
} else {
    // Class does not exist in the specified namespace
}
