How to get all image tags from an html - php code

Problem Statement

I wanted to fetch all image tags from a big html, and wanted to perform some check on the ’src’ value of img tag. This blog is about how I did that.

Solution

See the code below:

$doc = new DOMDocument();
$doc->loadHTML($body);
$tags = $doc->getElementsByTagName('img');
$imgArr = array();

//iterate over all image tags
foreach ($tags as $tag) {
  //get src attribute of an img tag
  $imgSrc = $tag->getAttribute('src');

  //Do your processing with any attribute of img tag
}
