How can the issue of overwriting $row be avoided in PHP?

The issue of overwriting $row in PHP can be avoided by using a different variable name to store the data fetched from a database query. This ensures that the original $row variable is not accidentally overwritten during subsequent iterations or operations. 

// Example of avoiding overwriting $row variable
$result = mysqli_query($connection, "SELECT * FROM table");

while ($row = mysqli_fetch_assoc($result)) {
    // Process data from $row
}

// $row variable is not overwritten and can be safely used outside the loop
