When does a PHP issue arise when trying to display multiple data sets in a specific format?

When trying to display multiple data sets in a specific format in PHP, an issue can arise if the data sets are not properly formatted or if there is a conflict in the way they are being displayed. One way to solve this issue is to use loops to iterate through each data set and format them accordingly before displaying them. 

<?php
// Sample data sets
$dataSet1 = ['John', 'Doe', '30'];
$dataSet2 = ['Jane', 'Smith', '25'];

// Loop through each data set and display in a specific format
foreach([$dataSet1, $dataSet2] as $data) {
    echo implode(' - ', $data) . "<br>";
}
?>
