Get all images url from string [duplicate]

Answer 1

This is what I tried but can't get it print value of src

 $dom = new domDocument;

    /*** load the html into the object ***/
    $dom->loadHTML($html);

    /*** discard white space ***/
    $dom->preserveWhiteSpace = false;

    /*** the table by its tag name ***/
    $images = $dom->getElementsByTagName('img');

    /*** loop over the table rows ***/
    foreach ($images as $img)
    {
        /*** get each column by tag name ***/
        $url = $img->getElementsByTagName('src');
        /*** echo the values ***/
        echo $url->nodeValue;
        echo '
';
    }

EDIT: I solved this problem

$dom = new domDocument;

/*** load the html into the object ***/
$dom->loadHTML($string);

/*** discard white space ***/
$dom->preserveWhiteSpace = false;

$images = $dom->getElementsByTagName('img');

foreach($images as $img)
    {
        $url = $img->getAttribute('src');   
        $alt = $img->getAttribute('alt');   
        echo "Title: $alt
$url
";
    }
