Yeah that's right. You have another device to worry about next time you want launch that big hit of a website you've been brewing for month. It's the iPad.

The iPad might not be exactly ipod touch's big brother but it does come with a browser twice as large as the ipod/iphone. For developers it's another agent we must take care of. Why? Because it opens up new opportunities for developers and there's thousands of hungry app consumers waiting for your next tap tap revenge. It's crazy. As Jobs puts it : "...If you're a dev, that's a plum market to go after...".

Actually there are many ways this can be achieved. There are some efficient ways and some quick ones. Below is one quick and simple way of checking if a string has html tags or not.

/**
 * This function will return true is the string contains html tags and false otherwise
 */
function hasHtml($str){
  //we compare the length of the string with html tags and without html tags
  if(strlen($str) != strlen(strip_tags($str)))
      return true;  
  return false;
}
