What is the significance of changing the || operator to && in the if condition?

Changing the || operator to && in an if condition will alter the logic of the statement. Using && means that both conditions must be true for the block of code to execute, whereas using || means that either condition being true will trigger the block of code.

// Original if condition with ||
if ($condition1 || $condition2) {
    // Code block
}

// Updated if condition with &&
if ($condition1 && $condition2) {
    // Code block
}
