Find image src with regex in PHP

Question

How can I extract image src from an text that only contains img tag? And by the way src is double quote sometimes and in single quote sometimes.

i only have string that contains some description of data that may have a img element — Aref Anafgeh, Aug 15 '15 at 06:56

For both quote styles try something [like this](https://regex101.com/r/wV0uS7/2): `\ssrc\s*=\s*['"]\s*\K[^'"\s]+` — Jonny 5, Aug 18 '15 at 16:00

I would not recommend using regex to parse html. Instead you can use php's DOMDocument() class, which should still work even if the rest of the string isn't really html:

$html = 'Lorem ipsum<img src="test.png">dolor sit amet&[H*()';

libxml_use_internal_errors(true);
$dom = new DOMDocument();
$dom->loadHTML($html);
$imgs = $dom->getElementsByTagName('img');
foreach($imgs as $img) {
    $src = $img->getAttribute('src'); 
    echo $src;
}

Depending on your php version you may also want to use:

$dom->loadHTML($a, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

Try

$image = '<img class="foo bar test" title="test image" src=\'http://example.com/img/image.jpg\' alt="test image" width="100" height="100" />';
$array = array();
preg_match( "/src='([^\"]*)'/i", $image, $array ) ;
print_r( $array[1] ) ;

this works fine but the problem is that src attr is sometimes in single quote and in that case your code does not work – Aref Anafgeh Aug 15 '15 at 06:49
If my answer works fine for you then why you did not accept my answer? – Muhammad Hassaan Aug 15 '15 at 09:31
well your answer works but according to my research using REGEX for this kind of problems is not best Way.using DOMDocuments is more reliable – Aref Anafgeh Aug 15 '15 at 09:48
@ArefAnafgeh You ask about `regex` so I give you answer according to `regex`. You did mention in your question to get best way of exporting images from web. Btw `regex` is more speedy way. – Muhammad Hassaan Aug 15 '15 at 10:22
