Extracting Image “src” Attributes from an HTML String using PHP

Here are a few ways to build an array of image sources extracted from an HTML string. I’m sure there are other ways, but these seem to be reliable.

$doc = new DOMDocument();
@$doc->loadHTML($html);
$tags = $doc->getElementsByTagName('img');
$image_srcs = array();
foreach ($tags as $tag) {
  $image_srcs[] = $tag->getAttribute('src');
}

$doc = new DOMDocument();

@$doc->loadHTML($html);

$tags = $doc->getElementsByTagName('img');

$image_srcs = array();

foreach ($tags as $tag) {

$image_srcs[] = $tag->getAttribute('src');

}

$images = array();
preg_match_all('/<img[^>]+>/im', $html, $images);
$image_srcs = array();
foreach ($images[0] as $image) {
 preg_match('/src="([^"]*)"/im', $image, $matches);
 $image_srcs[] = $matches[1];
}

$images = array();

preg_match_all('/<img[^>]+>/im', $html, $images);

$image_srcs = array();

foreach ($images[0] as $image) {

preg_match('/src="([^"]*)"/im', $image, $matches);

$image_srcs[] = $matches[1];

}
