parsing URL

cody7

What are the sites that you can recommend that talk about parsing URL, because i want to extract information on a website dynamically w/o doing the copy paste thing.

Thank you in advance...

Look here if I understand your question correct.
file()

What type of information are you trying to extract?

cody7

if i could extract all href="all_sites" involve in a certain site, or i can extract all value="all_values" attribute of an <option> tag, all text inside a <th></th> tag.

I want to extract what i want.

I heard of preg_match_all() would do the trick but is there another way of doing this stuff.

Thank you for any answer...

I know how to use regular expression to match things in [man]ereg()[/man], but I don't know for sure how you would loop through each match...

I could think of a really complicated way, but you're probably better off with preg_match_all, though I don't know how to write PERL's regular expressions.

Sorry. 🙁

cody7

Thank you sir for the information...

Maybe i'll just study how to use the prg_match_all() becoz accrd to the PHP manual preg_match() is often a faster alternative to ereg().

But still i'll consider testing ereg() in term of functionality.

Again thank you sir...

They're the same, except with additional functions. Just stick delimiters on the ends of a POSIX regexp and you've got a PCRE one (though probably not the most efficient).

Like...

$pattern = "|POSIX here|i";

does case-insensitive PCRE?
