Getting HTML pages in a variable

[Anon]

How do I get an html page into a variable?

For example, if I am looking to get a page at an address (http://www.foo.com/), and perhaps I just want to pull the cost of purchasing foobars and display it on my site, is there a way to do this? Once I get the page in a variable I can figure out the rest.

Use the file function and then you can pull out content line by line:

$fcontents = file ($filename);

while (list ($line_num, $line) = each ($fcontents)) {
echo "<b>Line $line_num:</b> " . htmlspecialchars ($line) . "<br>\n";
}

a more comfortable way that I often use:
$data = file("http://bla.bla.com/");

and, if you don't want $data to be an array containing one line per element:

$alldata = implode("", $data);
now it's in one string.

see implode() doc for details on this.
