getting image src in php

Question

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

Answer 1

Or, you can use the built-in DOM functions (if you use PHP 5+):

$doc = new DOMDocument();
$doc->loadHTMLFile($url);
$xpath = new DOMXpath($doc);
$imgs = $xpath->query("//img");
for ($i=0; $i < $imgs->length; $i++) {
    $img = $imgs->item($i);
    $src = $img->getAttribute("src");
    // do something with $src
}

This keeps you from having to use external classes.
