How can debugging techniques be effectively used to troubleshoot issues with reading and manipulating data in PHP scripts?

Issue: When reading and manipulating data in PHP scripts, it can be challenging to identify where errors are occurring. One effective way to troubleshoot these issues is by using debugging techniques such as printing out variable values, using error logs, and step-by-step debugging tools. PHP Code Snippet: 

// Example code snippet for debugging data manipulation issues
$data = [1, 2, 3, 4, 5];

// Print out the data array
print_r($data);

// Manipulate the data array
foreach($data as $key => $value) {
    $data[$key] = $value * 2;
}

// Print out the manipulated data array
print_r($data);
