What are the drawbacks of using a delimiter like "|" in a data format for storing user information in PHP?

Using a delimiter like "|" in a data format for storing user information in PHP can cause issues when the user input contains the delimiter itself. This can lead to data corruption or parsing errors when trying to extract the information. To solve this issue, you can use a different delimiter that is less likely to be included in user input, such as a comma or a tab.

// Using a comma delimiter to store user information
$userInfo = "John Doe,30,email@example.com";

// Split the user information using the comma delimiter
$userData = explode(",", $userInfo);

// Access the user data
$name = $userData[0];
$age = $userData[1];
$email = $userData[2];

// Output the user data
echo "Name: $name, Age: $age, Email: $email";
