使用preg_match正则表达式PHP解析HTML [重复]

• How do you parse and process HTML/XML in PHP? 30 answers

I want to parse the amount of hits a certain google search contains and store that in a PHP variable.

Example:

http://www.google.co.uk/search?as_epq=hello

returns a page containing: 'About 1,830,000,000 results' under the search bar.

All I want to take is the 1830000000 bit.

I'm pretty sure I use preg match but am completely useless at reg expressions, never been able to get my head around it.

The closet I have come is:

$adamHTML = file_get_contents('http://www.google.co.uk/search?as_epq=hello');

preg_match('/About/', $adamHTML, $return);

print_r($return);

Which gives me all the instances of 'About'. But how do I grab the number?

Thanks for any help...

It's bad, really bad. But you can use this.

preg_match('/About ([0-9,]+) results/', $adamHTML, $return);
