What are the potential pitfalls of not using proper syntax, such as missing quotation marks, when storing and retrieving text data in PHP?

Not using proper syntax, such as missing quotation marks, when storing and retrieving text data in PHP can lead to syntax errors and unexpected behavior in your code. It can also make your code harder to read and maintain. To avoid these pitfalls, always ensure that you properly enclose text data in quotation marks when storing and retrieving it in PHP.

// Incorrect way of storing and retrieving text data without proper syntax
$text = Hello World;
echo $text;

// Correct way of storing and retrieving text data with proper syntax
$text = "Hello World";
echo $text;
