How can errors in JSON decoding be effectively debugged in PHP?

When debugging errors in JSON decoding in PHP, it is important to check for syntax errors in the JSON string being decoded. One way to effectively debug this is to use the json_last_error() function to get the last JSON error that occurred during decoding. This can help identify issues such as invalid JSON syntax or encoding problems. 

$jsonString = '{"key": "value"}'; // JSON string with potential decoding errors

$data = json_decode($jsonString);

if(json_last_error() !== JSON_ERROR_NONE){
    echo "Error decoding JSON: " . json_last_error_msg();
} else {
    // JSON decoding successful, continue processing data
    var_dump($data);
}
