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?
This can be acheived with the following:
<?php
$input = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
$domain = 'http://stats.pingdom.com/';
$rep['/href="(?!https?:\/\/)(?!data:)(?!#)/'] = 'href="'.$domain;
$rep['/src="(?!https?:\/\/)(?!data:)(?!#)/'] = 'src="'.$domain;
$rep['/@import[\n+\s+]"\//'] = '@import "'.$domain;
$rep['/@import[\n+\s+]"\./'] = '@import "'.$domain;
$output = preg_replace(
array_keys($rep),
array_values($rep),
$input
);
echo $output;
?>
Which will output links as follows:
/something
will become,
And
../something
will become,
But it will not edit "data:image/png;" or anchor tags.
I'm pretty sure the regular expressions can be improved though.
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 :D
You dont need php, you only need to use the html5 base tag, and put your php code in html body, you only need to do the following Example :
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<base href="http://yourdomain.com/">
</head>
<body>
<? $txt = file_get_contents('http://stats.pingdom.com/qmwwuwoz2b71/522741');
echo $txt; ?>
</body>
</html>
and all the files will use the absolute url
