What potential issue arises when variables are constantly overwritten within a while loop in PHP?

When variables are constantly overwritten within a while loop in PHP, the values of those variables will be lost on each iteration, potentially leading to unexpected behavior or incorrect results. To solve this issue, you can store the values of the variables in an array or another data structure on each iteration of the loop.

$values = array(); // Initialize an array to store the values

while ($condition) {
    // Your code inside the loop
    $value = // Some value that gets overwritten on each iteration
    $values[] = $value; // Store the value in the array
}

// Now you can access all the values stored in the array
foreach ($values as $val) {
    echo $val . "\n";
}
