What are the potential pitfalls of copying code from the internet without understanding its functionality in PHP development?

Potential pitfalls of copying code from the internet without understanding its functionality in PHP development include introducing security vulnerabilities, using outdated or inefficient code, and not being able to troubleshoot or modify the code effectively. To avoid these issues, it is important to thoroughly understand the code you are implementing and make sure it aligns with best practices. 

// Example of how to avoid potential pitfalls by understanding code functionality

// Before using code from the internet, take the time to understand how it works
// Research any unfamiliar functions or methods to ensure they are secure and efficient
// Test the code thoroughly in your own environment to verify its functionality and make any necessary modifications

// Here is a simple example of how to implement a basic function after understanding its functionality:

function calculateSum($num1, $num2) {
   return $num1 + $num2;
}

// Usage:
$sum = calculateSum(5, 10);
echo $sum; // Output: 15
