title: How to pass an array via $_GET in php?
body: <p>How can I pass one or more variables of type array to another page via $_GET?</p>
  
  <p>I always passed variable values in the form <code>?a=1&amp;b=2&amp;c=3</code></p>
  
  <p>What about passing <code>a=[1,2,3]</code> ?</p>
  
  <p>Do I need to write a for loop and append all the values?</p>
  
  <p>Thanks</p>
