How can you ensure that a SQL command executed in PHP is not being run multiple times unintentionally?

To ensure that a SQL command executed in PHP is not being run multiple times unintentionally, you can use a flag variable to track whether the command has already been executed. Set the flag variable to true after executing the SQL command and check this flag before executing the command again. 

<?php
// Initialize flag variable
$commandExecuted = false;

// Check flag before executing SQL command
if(!$commandExecuted){
    // Your SQL command here
    $sql = "SELECT * FROM table_name";
    $result = mysqli_query($connection, $sql);

    // Set flag to true after executing the command
    $commandExecuted = true;
}
?>
