What is the potential issue with using concatenation in variable names in a PHP for loop?

Using concatenation in variable names in a PHP for loop can make the code harder to read and maintain. It can also lead to potential errors or bugs if not handled properly. To solve this issue, you can use an array to store the values instead of creating multiple variables with concatenated names. 

$values = array(1, 2, 3, 4, 5);

foreach ($values as $value) {
    echo $value . "<br>";
}
