使用正则表达式从HTML获取图像src

Question

I have HTML like

<td class="td_scheda_modello_dati">

       <img src="/webapp/safilo/gen_img/p_verde.gif" width="15" height="15" alt="" border="0">

</td>

I want to extract the img src from this HTML using preg_match_all().

I have done this

preg_match_all('#<td class=td_scheda_modello_dati>(.*)<td>#',$detail,$detailsav);

It should give the whole img tag.But it doesn't give me the img tag. So what changes should be done to get the specific value?

Long story short: ideone

You should not use Regex, but instead an HTML parser. Here's how.

<?php
$html = '<img src="/webapp/safilo/gen_img/p_verde.gif" width="15" height="15" alt="" border="0">';
$xpath = new DOMXPath(@DOMDocument::loadHTML($html));
$src = $xpath->evaluate("string(//img/@src)");
echo $src;
?>
