Does including external files in if statements affect the performance of PHP scripts?

Including external files in if statements can affect the performance of PHP scripts because the file will be included every time the if statement is evaluated, even if the condition is false. To solve this issue, you can include the external file outside of the if statement and only execute the necessary code inside the if block. 

// Include the external file outside of the if statement
require_once 'external_file.php';

// Check the condition and execute code accordingly
if ($condition) {
    // Code to execute when condition is true
}
