What are the best practices for error reporting in PHP to avoid notices like "Undefined variable"?

To avoid notices like "Undefined variable" in PHP, it is best practice to always initialize variables before using them. This can be done by assigning a default value to the variable or checking if it is set using isset() function before using it in your code. 

// Example of initializing a variable to avoid "Undefined variable" notice
$variable = ''; // initializing the variable with a default value

if(isset($variable)){
    // do something with the variable
} else {
    // handle the case when the variable is not set
}
