What are the potential pitfalls of switching between PHP and JavaScript within an IF loop for database operations?

Switching between PHP and JavaScript within an IF loop for database operations can lead to confusion and potential errors due to the different syntax and execution environments of the two languages. It is recommended to stick to using one language consistently for database operations to maintain code clarity and reduce the likelihood of bugs.

<?php
// Example of using only PHP for database operations within an IF loop

if ($condition) {
    // PHP code for database operations
    $connection = mysqli_connect("localhost", "username", "password", "database");
    $query = "SELECT * FROM table";
    $result = mysqli_query($connection, $query);
    
    // Process the database query result
    while ($row = mysqli_fetch_assoc($result)) {
        // Handle each row of data
    }
    
    // Close the database connection
    mysqli_close($connection);
}
?>
