How can proper variable naming conventions prevent errors like "Notice: Undefined variable" in PHP scripts?

Improper variable naming conventions can lead to errors like "Notice: Undefined variable" in PHP scripts because PHP is a loosely typed language, meaning variables do not need to be declared before use. To prevent this error, it's important to follow proper naming conventions and initialize variables before using them in your code.

// Example of using proper variable naming conventions to prevent "Notice: Undefined variable" error
$myVariable = "Hello, World!"; // Initialize the variable before using it

echo $myVariable; // Output: Hello, World!
