Question

I am requesting the source code of a website like this:

<? $txt = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
echo $txt; ?>

Bu I would like to replace the relative links with absolute ones! Basically,

<img src="/images/legend_15s.png"/> and <img src='/images/legend_15s.png'/>

should be replaced by

<img src="http://domain.com/images/legend_15s.png"/> 

and

<img src='http://domain.com/images/legend_15s.png'/>

respectively. How can I do this?

Answer 1

This code replaces only the links and images:

<? $txt = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
$txt = str_replace(array('href="', 'src="'), array('href="http://stats.pingdom.com/', 'src="http://stats.pingdom.com/'), $txt);
echo $txt; ?>

I have tested and its working 🙂

UPDATED

Here is done with regular expression and working better:

<? $txt = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
$domain = "http://stats.pingdom.com";
$txt = preg_replace("/(href|src)\=\"([^(http)])(\/)?/", "$1=\"$domain$2", $txt);
echo $txt; ?>

Done 😀
