Check if a class exists in PHP

To check whether a class exists or not in PHP, you need to use the class_exists() function.

Call the class_exists() function and pass the class name as a string parameter to that function:

// 👇 check if a class named Human exists

The function will return either true or false. Combine it with an if block to create conditional branch as shown below:

    print "The Human class exists";
} else {
    print "Class does not exists";

And that’s how you check whether a class exists or not in PHP. Nice! 👍
