What potential security risks are associated with using $GLOBALS in PHP?
Using $GLOBALS in PHP can pose security risks as it allows global access to variables across all scopes, making it vulnerable to unintended modification or manipulation. To mitigate this risk, it is recommended to avoid using $GLOBALS and instead use more localized variable scopes like function parameters or class properties.
// Avoid using $GLOBALS and use localized variable scopes instead
function exampleFunction($param) {
// Use $param instead of $GLOBALS['param']
// Your code here
}
