title: Examples of XSS that I can use to test my page input?
body: <p>I have had issues with XSS. Specifically I had an individual inject JS alert showing that the my input had vulnerabilities. I have done research on XSS and found examples but for some reason I can't get them to work.</p>
  
  <p>Can I get example(s) of XSS that I can throw into my input and when I output it back to the user see some sort of change like an alert to know it's vulnerable?</p>
  
  <p>I'm using PHP and I am going to implement htmlspecialchars() but I first am trying to reproduce these vulnerabilities.</p>
  
  <p>Thanks! </p>
