Preg_match fustratoins

I am getting so mad can someone look at this I am trying to learn how to scrape parts off a website:

<?php
$data = file_get_contents('http://search.msn.com/results.aspx?q=site%3Afroogle.com');
$regex = '/Page 1 of (.+?) /results/div id="search_header"><h1>site:froogle.com</h1><h5>Page 1 of 9,138 results</h5>&nbsp;<b>&#01/';
preg_match($regex,$data,$match);
var_dump($match);
?>

error:

Warning: preg_match() [function.preg-match]: Unknown modifier 'r' in idcidkidcidkidc.php on line 4
NULL

please help

 

I think you have to escape the '/' that appears before r.

Not sure, not a big regex expert.

Try putting a '\' in front of all of those and see what happens.

 

Me ethier lol as you can tell i am a n00b

 

You are using slash as delimiters and the regex itself contains some slashes. So either escape the slashes in the regex by adding a backslash in front of them, or use a different character as delimiters (e.g.: $regex = '|Page 1 of ... &nbsp;<b>&#01|';

 

Can someone give me an example of how to do this I can a n00b I dont know what u mean by escape the slashes. Can someone explain to a n00b how to do this?

 

Lesson 1: Escaping

What would you do if you want a newline character in a string?

$sting = "this is a \n newline.";

PHP:

What if you want a double quote? Sure you can alternate it.

$string = 'This string contains a " in it';

PHP:

Or you can "escape" it.

$string = "This string contains a \" in it";

PHP:

In your case:
I would just use a different deliminator

$regex = "%Page 1 of (.+?) /results/div id=\"search_header\"><h1>site:froogle.com</h1><h5>Page 1 of 9,138 results</h5>&nbsp;<b>%";

PHP:

or do it the hard way.

$regex = "/Page 1 of (.+?) \/results\/div id=\"search_header\"><h1>site:froogle\.com<\/h1><h5>Page 1 of 9,138 results<\/h5>&nbsp;<b>/";

PHP:
