PHP使用DOM提取img src，并在文本中保留其位置[复制]

This question already has an answer here:

So I'm building a simple HTML scrapper, in the text there are some images for the symbols and what I need is to get the src of this img tags, but keep them in the same place as the img tags where in the text.

--question rewritten due to me being asking the wrong thing.

Since you're using DOM parser so you can extract image's src attribute in a variable. After that use following code:

$imgsrc = '/Handlers/Image.ashx?size=small&amp;name=3&amp;type=symbol';
$url = parse_url($imgsrc);
$query = htmlspecialchars_decode($url['query']);
parse_str($query, $arr);
echo $arr['name'] . "
"; // prints 3

Well, I'd really suggest using a proper HTML parsing library to do this, but if it's really simple you can get away with a regex like /<img[^>]*alt="(\d+?)"/ or so.

if you want to get the name= part from the src attribute which is /Handlers/Image.ashx?size=small&amp;name=3&amp;type=symbol you can try this

<?php
$src = '/Handlers/Image.ashx?size=small&amp;name=3&amp;type=symbol';
$x = preg_replace('/^.*name=([^&]*).*$/i','[$1]',$src);
echo $x;
?>
