im trying to get the inner content of a span tag from google.com’s home site. this code should output the first span tag, but it is not outputting any results?

Answer 1

The is not an error … the first span in http://www.google.com is empty and am not sure what else you expect

 <span class=gbtcb></span> <----------------  item(0)
 <span class=gbtb2></span> <----------------  item(1)
 <span class=gbts>Search</span> <-----------  item(2)

Try

$element = $doc->getElementsByTagName('span')->item(2);
var_dump($element->nodeValue);

Output

Search
