Help with Php and Regex

[The.Relinator]

I'm just wondering what the best way is to extract and display a
number from a html file.

I tried the following piece of code, however it does not work.

ereg('\d\.\d', $content, $reg);
echo $reg[0];

ereg() is a test function, it checks if a regexp matches a given string
and returns a boolean.
You probably need ereg_replace($regexp, $substitute, $input); see the
doc for details.

Don't use ereg, it's deprecated.

preg_match_all('/-? ( \d+\.?\d* | \.\d+) /x', $html, $matches);

finds numbers like "12", "-123.456" and ".789" and places them in array
$matches.
