如何在HTML标记中获取图像URL？

Question

I need to get proper image for each article. Every single image is saved among different HTML tags in different rows in database. So how should I get img URL with PHP code?

 <p><img src="images/akhbar/5/q103.jpg" alt="q103" style="display: block; margin-left: auto; margin-right: auto;" height="315" width="675" /></p>
