What is the significance of the variable $aHit in the context of the code?

The variable $aHit is likely used to track whether a hit has occurred in the code. To fix the issue, we need to ensure that $aHit is properly initialized before being used. This can be done by setting $aHit to false before any conditional checks or assignments.

$aHit = false;

// Code logic that may change the value of $aHit

if ($aHit) {
    // Do something if a hit has occurred
} else {
    // Do something if no hit has occurred
}
