How can developers avoid common mistakes when working with JSON data in PHP?

Developers can avoid common mistakes when working with JSON data in PHP by properly encoding and decoding data using the json_encode() and json_decode() functions, handling errors that may occur during encoding or decoding, and validating input data to ensure it is in the correct format before processing. 

// Example of encoding data to JSON
$data = array("name" => "John", "age" => 30);
$json_data = json_encode($data);
if($json_data === false){
    // Handle error
    die("Error encoding JSON data");
}

// Example of decoding JSON data
$json_string = '{"name": "Jane", "age": 25}';
$decoded_data = json_decode($json_string, true);
if($decoded_data === null){
    // Handle error
    die("Error decoding JSON data");
}
