how to get link from img tag

$img = '<img src="http://some-img-link" alt="some-img-alt"/>';

$src = preg_match('/<img src=\"(.*?)\">/', $img);

echo $src;

I want to get the src value from the img tag and maybe the alt value

Solution

  • Assuming you are always getting the img html as you shown in the question.

    Now in the regular expression you provided its saying that, after the src attribute its given the closing tag for img. But in the string there is an alt attribute also. So you need to care about it also.

    /<img src=\"(.*?)\".*\/>/

    And if you are going to check alt also then the regular expression.

    /<img src=\"(.*?)\"\s*alt=\"(.*?)\"\/>/

    Also you are just checking whether its matched or not. If you need to get the matches, you need to provide a third parameter to preg_match which will fill with the matches.

    $img = '<img src="http://some-img-link" alt="some-img-alt"/>';
$src = preg_match('/<img src=\"(.*?)\"\s*alt=\"(.*?)\"\/>/', $img, $results);
var_dump($results);

    Note : The regex given above is not so generic one, if you could provide the img strings which will occur, will provide more strong regex.
