Are there specific PHP functions or configurations that can help troubleshoot issues with data transmission between JavaScript and PHP?

To troubleshoot issues with data transmission between JavaScript and PHP, you can use PHP functions like json_encode() and json_decode() to encode and decode data in a format that can be easily transferred between the two languages. Additionally, you can check for any errors in the data transmission process by using functions like isset() or empty() to ensure that the data is being properly sent and received. 

// Example code snippet to encode data in PHP before sending it to JavaScript
$data = array('name' => 'John', 'age' => 30);
$json_data = json_encode($data);
echo $json_data;
```
```php
// Example code snippet to decode data in PHP after receiving it from JavaScript
$json_data = '{"name":"John","age":30}';
$data = json_decode($json_data, true);
print_r($data);
