What are potential causes for JSON parsing issues in PHP scripts?

Potential causes for JSON parsing issues in PHP scripts include malformed JSON syntax, encoding mismatches, or invalid JSON data being passed to the parser. To solve this issue, you can use error handling functions like json_last_error() and json_last_error_msg() to identify the problem with the JSON data being parsed. 

$jsonData = '{"name": "John", "age": 30, "city": "New York"}';

// Attempt to decode the JSON data
$decodedData = json_decode($jsonData);

// Check for JSON parsing errors
if (json_last_error() !== JSON_ERROR_NONE) {
    echo "JSON parsing error: " . json_last_error_msg();
} else {
    // JSON data was successfully parsed
    var_dump($decodedData);
}
