How can the presence of backslashes in decoded JSON strings indicate a specific issue with PHP decoding functions?

When decoded JSON strings contain backslashes, it indicates that the string has been escaped twice. This can happen when using functions like json_encode() followed by addslashes() before encoding. To solve this issue, you can use the stripslashes() function in PHP to remove the extra backslashes before decoding the JSON string.

$jsonString = '{"name": "John Doe", "email": "john.doe@example.com"}';
$decodedString = json_decode(stripslashes($jsonString), true);

// Accessing the decoded values
$name = $decodedString['name'];
$email = $decodedString['email'];

echo $name; // Output: John Doe
echo $email; // Output: john.doe@example.com
