In the context of PHP programming, how can developers effectively troubleshoot and debug issues related to array manipulation and variable assignments?

When troubleshooting array manipulation and variable assignment issues in PHP, developers can use built-in functions like var_dump() or print_r() to inspect the contents of arrays and variables at different points in the code. Additionally, using error reporting functions like error_reporting(E_ALL) and ini_set('display_errors', 1) can help identify any syntax or logic errors that may be causing problems. 

// Example code snippet demonstrating the use of var_dump() and error reporting functions for troubleshooting array manipulation and variable assignment issues

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Sample array manipulation and variable assignment
$numbers = [1, 2, 3, 4, 5];
$sum = 0;

foreach ($numbers as $number) {
    $sum += $number;
}

// Debugging output
var_dump($numbers);
var_dump($sum);
