How can PHP developers effectively troubleshoot and debug issues related to array manipulation and data conversion in their code?

To effectively troubleshoot and debug issues related to array manipulation and data conversion in PHP, developers can use functions like var_dump(), print_r(), and die() to inspect the contents of arrays at different stages of manipulation. Additionally, using error reporting functions like error_log() can help identify any conversion errors or unexpected behavior. Finally, utilizing PHP's built-in functions for array manipulation and data conversion, such as json_encode() and json_decode(), can aid in resolving issues.

// Example code snippet demonstrating troubleshooting and debugging array manipulation and data conversion issues

// Sample array manipulation
$originalArray = [1, 2, 3];
$newArray = array_map(function($value) {
    return $value * 2;
}, $originalArray);

// Debugging using var_dump()
var_dump($newArray);

// Data conversion example
$data = '{"name": "John", "age": 30}';
$decodedData = json_decode($data, true);

// Debugging using print_r()
print_r($decodedData);
