Question

I have php variable which when echoed, blurts out the html. But I was to (somehow!) just get the image code out. Essentially, I want to do a grep on the variable for the image code.

How can I do this? Everything I’ve tried (stripos, strstr) doesn’t work because it prints it all out in html. How can I first just output the code in plain text and not html?

Thanks

Depending on the HTML the variable contains, I would either

• call the strip_tags function: http://php.net/manual/en/function.strip-tags.php
• load the HTML into a DOM object and navigate your way to the desired information. Built-in DOM for PHP: http://php.net/manual/en/class.domdocument.php
  • you can then try to find an element with either getElementsByTagName or getElementById

Where is the info you’re looking for located exactly? Maybe you could post an example.
