What are common causes of PHP encountering Access Violations?

Access violations in PHP commonly occur when trying to access an undefined variable, array index, or object property. To solve this issue, make sure to properly initialize variables before using them and check if array keys or object properties exist before accessing them. 

// Example of preventing access violations by checking if array key exists
$array = ['key' => 'value'];

if (array_key_exists('key', $array)) {
    echo $array['key'];
} else {
    echo "Key does not exist";
}
