How can debugging be effectively conducted in a PHP script for a PLZ Umkreissuche to ensure accurate results for different distances and locations?

To effectively debug a PHP script for a PLZ Umkreissuche (radius search), one can start by checking the input parameters, ensuring they are correctly passed and parsed. Additionally, logging intermediate results or using print statements can help track the flow of the script and identify any potential errors. Testing the script with different distances and locations can also help ensure accurate results.

<?php
// Sample PHP script for PLZ Umkreissuche debugging

// Input parameters
$plz = $_GET['plz']; // Get the postal code
$distance = $_GET['distance']; // Get the distance

// Debugging
echo "Postal code: " . $plz . "<br>";
echo "Distance: " . $distance . " km<br>";

// Your radius search logic goes here

// Sample output
echo "Results for PLZ Umkreissuche:<br>";
// Output the results
?>
