What are the potential pitfalls of not initializing variables before using them in PHP?

If variables are not initialized before using them in PHP, it can lead to unexpected behavior or errors in the code. It is important to initialize variables to avoid issues such as undefined variable errors or unintended values being assigned to them. To solve this problem, always make sure to declare and initialize variables before using them in your PHP code.

// Initializing variables before using them
$variable = ""; // Initializing with an empty string or appropriate default value
// Now you can safely use the variable without any issues
