Downloading and parsing web-stuff

[David Rasmussen]

Very basic:

What is the easiest way in php to download the source code (HTML etc.)
of a given URL (say, http://www.google.com) and parse this code for
certain patterns?

I guess my question can be split in two:

1) How do I download a webpage (into a string or whatever)?

2) How can I do string manupulation, regexp matching, information
extraction etc. on the downloaded information?

$string = file_get_conten ts('http://some.url/blah');

now look at the docs for preg_match or ereg
I prefer preg_match

if ( preg_match('|<t itle>(.*?)</title>|',$strin g,$matches) )
{
print_r($matche s);
}

Re: Downloading and parsing web-stuff

Treat a full URL as a file.

$contents = implode( file("http://www.google.com/", ''\n") );

Then go to www.php.net/preg_match/ to read up on PCRE (Perl compatible
regular expressions). See also ereg_* functions.

HTH.
