How to insert html code inside an array in PHP?

I tried searching on internet but found nothing.

$html = array
('<IFRAME src="http://link1.com" width="1" height="1" 
scrolling="auto" frameborder="0"></IFRAME>' ,

'<IFRAME src="http://link2.com" width="1" height="1" 
scrolling="auto" frameborder="0"></IFRAME>' ,

'<IFRAME src="http://link3.com" width="1" height="1" 
scrolling="auto" frameborder="0"></IFRAME>');
print_r ($html);

When I tried to print_r, there was no result.

There is no result because you are giving the output to the browser, which happily places three <iframe>s with invalid source URLs in your page. So you see nothing for the same reason you would see nothing if you did print '<p></p>';.

If you view the page source you will see your HTML is there.

Normally to see HTML markup as “plain text” you would need to pass it through htmlspecialchars — however, that function works with strings and here you have an array. So if you want to print the contents as human-readable text, you need to do something fancier and use array_map:

print_r(array_map('htmlspecialchars', $html));
