PHP open link in iframe

Answer 1

I don't know if I understood your question, but maybe you want to do this:

echo '<iframe src="http://www.google.ca/search?hl=en&amp;source=hp&amp;fkt=3948&amp;fsdt=45174&amp;q=$check imdb&btnI=I%27m+Feeling+Lucky&meta=&aq=f&oq=" />';

Answer 2

You did not include the source for the iframe itself, but basically, all you have to do is echo the URL into the iframe's src attribute:

echo '<iframe id="imdb" src="'.'http://www.google.ca/search?hl=en&amp;source=hp&amp;fkt=3948&amp;fsdt=45174&amp;q=$check imdb&btnI=I%27m+Feeling+Lucky&meta=&aq=f&oq="></iframe>';
