How can one ensure proper initialization of variables before using them in PHP code?

To ensure proper initialization of variables before using them in PHP code, it is important to always assign a default value to variables before using them. This prevents potential issues such as undefined variable errors or unexpected behavior in your code. You can initialize variables with default values at the beginning of your script or function to ensure they are properly set before any operations are performed. 

// Initialize variables with default values
$variable1 = '';
$variable2 = 0;

// Use the variables after initialization
echo $variable1;
echo $variable2;
