Question

how to get image source from an img tag using php function.

Answer 1

Consider taking a look at this.

I’m not sure if this is an accepted method of solving your problem, but check this code snippet out:

// Create DOM from URL or file
$html = file_get_html('http://www.google.com/');

// Find all images 
foreach($html->find('img') as $element) 
       echo $element->src . '<br>';

// Find all links 
foreach($html->find('a') as $element) 
       echo $element->href . '<br>';
