Re: [PHP] Loop within Loop help please

[Eduardo Sampaio]

You missed the $count = 0;
right below it Andrew... his code works just like the modulus one...

  $count = 0;
  foreach . {
 if($count == 20) {
  .
 
 The only thing wrong with this method is that it doesn't fit the
 problem's specifications.The original poster wanted a way to
 trigger the code every 20 iterations of an unknown sized loop
 (implying that the loop would have 40 or more items), whereas the
 solution above only triggers it on iteration 20.  Other than that,
 it's a perfectly wonderful piece of code.

Re: [PHP] Re: grabbing information from websites

[Eduardo Sampaio]

I agree with Trevor... but if he manages to nvigate to the page and
try to parse it, he will end up finding the problem Graham said. He is
only reading the first line. He can either use fread or shrink his
regex to #align=right([0-9]*,?[0-9]*)/td# and make a loop using
fgets. The second option is the worse one tough, the website probably
has way more lines matching that criteria... But it works on that
small piece of the source.

 The URL that you're grabbing there is a frameset, it's probably not the

 When you right-click on the page you want to parse and select View
 Source and get the information you posted below, do the same thing but
 right-click and select Properties (in IE at least) and it'll tell you
 the URL that you're really looking at.
 
 My guess is that you're really parsing this source:

 Try echo'ing $line and looking at the data you're parsing.  I bet it's

  i said i was learning this and didnt really understand it.
  so going by what has been said i have come up with the
  following but
  still doesnt want to work.
  heres what i have:
 
  ?php
  $file = fopen
  (http://hiscore.runescape.com/aff/runescape/hiscorepersonal.c
  gi?username=champinoman,r);
  $line = fgets ($file, 1024);
  if
  (preg_match('#username=champinomancategory=13.*align=right
  (.*)/td#mi',$line,$out))
  {
  $rune = $out;
  }
  fclose($file);
  print $rune;
  ?
 
  and the source it is looking at is:
 
  trtdimg src=http://www.runescape.com/img/hiscores/crafting.gif;
  valign=bottom width=16 height=16 //tdtdnbsp;/td
  tda href=hiscoreuser.cgi?username=champinomancategory=13
  class=cCrafting/a/td
  td align=right70,277/tdtd align=right
  43
  /tdtd align=right
  53,630
  /td/tr
 
  I want it to get the 70,277 and store as $rune
  if someone can tell me where im wrong i would be extremely grateful
 
  thank you for your ongoing support.

   ugh, obviously I'm a bad typer :) The code should be:
  
  
  preg_match('#username=champinomancategory=13.*align=right(
  .*)/td#mi',
   $text, $out);
  
   Or using any other patterndelimiter... ;)

   I thought I clearly stated that for the m modifier you
  need to use PCRE
   functions!
  
   eg:
  
  
  preg_match('/username=champinomancategory=13.*align=right(
  .*)/td/mi',
   $text, $out);

   so does this look right:
  
   eregi
  
  (username=champinomancategory=13.*align=\right\(.*)/td
  m,$line,$out))
  
   is that where i am ment to put the 'm' modifier? or am i
  still off on
   the wrong track?

  Sometimes you have a programming problem and it seems like the
 best
  solution is to use regular expressions; now you have two problems.
 
  To me regular expressions are some kind of black art, I've been
  programming
  for 20 years and until recently have pretty much managed to avoid
 them.
  The
  above URL is a pretty good tutorial.
