How can beginners effectively debug PHP scripts and identify the root cause of errors like "Trying to access array offset on value of type bool"?

To effectively debug PHP scripts and identify the root cause of errors like "Trying to access array offset on value of type bool", beginners can start by checking if the variable being accessed is actually an array before trying to access its elements. This error typically occurs when trying to access an array index on a variable that is not an array, often due to incorrect data types or values being assigned. Using conditional checks to ensure the variable is an array before accessing its elements can help prevent this error. 

// Example code snippet to fix "Trying to access array offset on value of type bool" error
if (is_array($yourVariable)) {
    // Access the array element safely
    $value = $yourVariable['key'];
} else {
    // Handle the case where $yourVariable is not an array
    echo "Variable is not an array.";
}
