Extract an attribute from a specific element in DOM

I want to be able to extract only the src of the second image in an html file. I am using the PHP DOM parser:

foreach($html->find('img[src]') as $element)
        $src开发者_开发知识库 = $element->getAttribute('src');
        echo $src;

However, I am getting the src of the last image in the page, instead of the one I am looking for.

Can I display only a specific src outside of the foreach loop?

Your loop is missing {}, it is equivalent to

foreach($html->find('img[src]') as $element) {
        $src = $element->getAttribute('src');
}
echo $src;

so, the echo gets the $src after the last iteration of your loop, which is the last element.

Using the example from their website, I'd go with this (braces are key here):

$count = 1;
foreach($html->find('img') as $element) {
   if ($count == 2) {
     echo $element->src;
     break;
   }
   $count += 1;
}
