ya but that version includes the trailing \s

I was wondering if that was the best way to
get that trailing \s trimmed out.. i stumbled upon
the result with http:// included and the \s trimmed
out ... sort of thinking out loud and using it, i was thinking nested and sort of got
there by accident, not really getting it just yet... thats so
flexible it bends my brain a little trying to solve the puzzle
because the tools are there to tear a pattern out of infinite
possibilities..

$re = '/http:\/\/(.*?)\s/';

Code:

array
  0 =>
    array
      0 => string 'http://www.privacyrights.org/fs/fs6a-facta.htm ' (length=47)
      1 => string 'http://uspirg.org/uspirg.asp?id2=13649 ' (length=39)
      2 => string 'http://en.wikipedia.org/wiki/Fair_and_Accurate_Credit_Transactions_Act
' (length=71)
  1 =>
    array
      0 => string 'www.privacyrights.org/fs/fs6a-facta.htm' (length=39)
      1 => string 'uspirg.org/uspirg.asp?id2=13649' (length=31)
      2 => string 'en.wikipedia.org/wiki/Fair_and_Accurate_Credit_Transactions_Act' (length=63)

but with the outside parens i accidentally get array[1] which has that result i wanted
all cleaned up...

Code:

array
  0 =>
    array
      0 => string 'http://www.privacyrights.org/fs/fs6a-facta.htm ' (length=47)
      1 => string 'http://uspirg.org/uspirg.asp?id2=13649 ' (length=39)
      2 => string 'http://en.wikipedia.org/wiki/Fair_and_Accurate_Credit_Transactions_Act
' (length=71)
  1 =>
    array
      0 => string 'http://www.privacyrights.org/fs/fs6a-facta.htm' (length=46)
      1 => string 'http://uspirg.org/uspirg.asp?id2=13649' (length=38)
      2 => string 'http://en.wikipedia.org/wiki/Fair_and_Accurate_Credit_Transactions_Act' (length=70)

Um, what's the difference between array[0] and array[1]? I thought you were trying to scrape for what's seen in arr[2]...?

array0 includes a trailing slash, array1 does not.

Code:

<?php
$re = '/http:\/\/(.*?)\s/';

kinda clunky and very greedy. I'd try to tighten it up a bit.

Code:

<?php
$re = '/http:\/\/(\S+)\s/';

Keeping in mind this only works if you have whitespace after each URL. It'd fail parsing the links out of a page of HTML because you're not checking for quotes or anything. I use something like this:

Code:

<?php
$regex = '/href=[\'\"](\S+)[\'\"]/';

to strip all the links out of a page. \S is shorthand for "anything but whitespace". I also frequently just make a negated set with quotes in it like [^\'\"] since a URI can't contain quote characters.
