PHP从HTML代码中获取图像 - 简单

Question

I have a text editor on my web page, on that text editor i put image and than i use that image in different parts of my website, but in different places the image size differs.

The image in database is stored this way: <div><img width="210" height="150" alt="" src="/portali/userfiles/image/Kategorite/Teknologji/-1.jpg" /></div>

Now in one part of my web site i want to use this same image with different size and for this reason i need some php script to grab only the path of the image, in this sample (/portali/userfiles/image/Kategorite/Teknologji/-1.jpg).

Can some body write here some basic script to do this having in mind that the whole html code of the image is in an single variable.

Answer 1

$html = '<?xml version="1.0" encoding="UTF-8"?>'.$yourHTMLFromDb;
$elements = new SimpleXmlElement($html);
$url = $elements->img->attributes()->src;

Now im sure i wont be the first to say it but... "Youre doing it wrong". You should only be storing the path to the image in the database (and maybe some other attribnutes) not an html snippet.
