What are the potential risks of using the same variable names in PHP loops?

Using the same variable names in PHP loops can lead to conflicts and unexpected behavior, as the variables will be overwritten with each iteration. To avoid this issue, it is recommended to use unique variable names for each loop iteration. 

// Example of using unique variable names in PHP loops

// Using unique variable names
for ($i = 0; $i < 5; $i++) {
    $value = $i * 2;
    echo $value . "<br>";
}

// Using unique variable names
for ($j = 0; $j < 3; $j++) {
    $result = $j + 1;
    echo $result . "<br>";
}
