What are some potential drawbacks of providing direct code solutions without encouraging users to understand the underlying concepts?

Providing direct code solutions without encouraging users to understand the underlying concepts can lead to a lack of critical thinking and problem-solving skills. It may result in users being unable to troubleshoot or modify the code on their own. To address this issue, it's important to provide explanations alongside code solutions to help users grasp the logic and principles behind the code.

// Example of providing explanation alongside code solution
// Calculate the sum of two numbers

$number1 = 5;
$number2 = 10;

// Explanation of the code
$sum = $number1 + $number2;
echo "The sum of $number1 and $number2 is: $sum";
