title: How check if a variable is a date, string or float (numeric) [PHP]
body: <p>Hy guys, i have a problem.</p>
  
  <p>My variable can have different values in my cycle:</p>
  
  <ul>
  <li>values="10"</li>
  <li>values="Hello"</li>
  <li>values="2015-02-17"</li>
  </ul>
  
  <p>How do I check the type of variable with a condition? I have tried but string type is "equal" to date type.</p>
