How can unconventional key names with spaces in JSON data be handled effectively in PHP?

When dealing with unconventional key names with spaces in JSON data in PHP, you can handle them effectively by using curly braces and single quotes to access the keys. This allows you to access keys with spaces without any issues.

$jsonData = '{"first name": "John", "last name": "Doe"}';
$data = json_decode($jsonData, true);

// Accessing keys with spaces using curly braces and single quotes
$firstName = $data->{'first name'};
$lastName = $data->{'last name'};

echo $firstName . ' ' . $lastName; // Output: John Doe
