Retrieving information from another website

Question

Hi,

I'm looking for a method to get some information from another website (http://contests.covers.com/sportscontests/picksByDate.aspx?date=11/2/2007&ur=265839&contestID=15253&sportID=9) in an automated way. I need to get the total value of a NBA game between boston and another team (variable team) and if Boston got WIN or LOSS in its row.

I've tried this but I have a little problem:

<?php
$url = 'http://contests.covers.com/sportscontests/picksByDate.aspx?date=11/2/2007&ur=265839&contestID=15253&sportID=9&t=0';
 
$array = file($url);
 
$key = array_search('<table cellspacing="0" class="thepicks">
', $array);
 
$flop = $key + 12;
 
$result = $array[$flop];
 
print($result);
?>

This is a test script and it works. The way I want to retrieve my information is by searching the Boston team in the array (note that it is a link). The problem i'm facing is that I doesn't find: <td><a href="http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/team404117.html">New Jersey</a></td>
in my array. So the following code doesn't give me the right line. It takes array[0] +15 which is wrong.

<?php
$url = 'http://contests.covers.com/sportscontests/picksByDate.aspx?date=11/2/2007&ur=265839&contestID=15253&sportID=9&t=0';
 
$array = file($url);
 
$key = array_search('<td><a href="http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/team404117.html">New Jersey</a></td>
', $array);
 
$flop = $key + 15;
 
$result = $array[$flop];
 
print($result);
?>

The variable in the array (<td><a href="http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/team404117.html">New Jersey</a></td>) can be shown using the first code fragment. So it is surely displayable.

So does anyone know why he can't find this link (<td><a href="http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/team404117.html">New Jersey</a></td>) in my array?

Thanks is higly appreciated!

When you use file() it returns the array of lines including the line breaks at the end of the line. Theoretically you can use the FILE_IGNORE_NEW_LINES flag to retrieve lines without them...

$array = file($url,FILE_IGNORE_NEW_LINES);

But there seems to be an issue with that so you're better off either searching for a line with the breaks...

$key = array_search("<table cellspacing=\"0\" class=\"thepicks\">\r\n", $array);

Or using file_get_contents() instead of file() to return a string instead of a line array.

Did you read my post earlier about the line breaks? This is still that same issue. If you replace lines 21 and 22 with $key = array_search(" <td><a href=\"http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/team404169.html\">Boston</a></td>\r\n",$array); you get the correct key. Notice the line breaks at the end...\r\n. I also changed to double quotes because those escape codes don't work with single quotes. (So the quotes within the string had to be escaped as well)

I would guess it's taking too long to retrieve the document. I don't think there's any way to do a timeout on file() so maybe something else like curl or fsocketopen() would work better for getting the file. Either that or change the timeout time of your script with set_time_limit.

I have just gotten a little closer with the problem. I have this now:

<?php
require_once ('C:\wamp\www\mysql.php');

$connection = db_connect();

$maand = array("11","11","11");
$dag = array("2","4","7");
$jaar = array("2007","2007","2007");

$expert = 265839;

for ($i = 0; $i <= 2; $i++){

	$url = 'http://contests.covers.com/sportscontests/picksByDate.aspx?date=' . $maand[$i] .'/' . $dag[$i] . '/' . $jaar[$i] .'&ur=' . $expert . '&contestID=15253&sportID=9&t=0';
	
	$array = file($url);
	
	$key = array_search('		<td><a href="http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/team404169.html">Boston</a></td>
	',$array);
	
	$arraynba = $key - 1;
	
	$arraytest = $array[$arraynba];
	
	if($arraytest == "		<td>NBA</td>
	"){
		$sidepick = $key + 4;
		$totalpick2 = $key + 13;
	
		$result1 = $array[$sidepick];
		$result2 = $array[$totalpick2];
	
	
	} else {
	    $sidepick = $key + 4;
	    $totalpick2 = $key - 5;
	
	    $result1 = $array[$sidepick];
	    $result2 = $array[$totalpick2];
	}
	
	$datum = $maand[$i] . '/' . $dag[$i] . '/' .$jaar[$i];
	
	//De gegevens wegschrijven in de database
	$query = $connection->query("INSERT INTO nba (datum, boston, tegenstander) VALUES ('$datum','$result1', '$result2')");
	

	
}

But when I check my for loop with this:

require_once ('C:\wamp\www\mysql.php');

$connection = db_connect();

$maand = array("11","11","11");
$dag = array("2","4","7");
$jaar = array("2007","2007","2007");

$expert = 265839;

for ($i = 0; $i <= 2; $i++){

	$url = 'http://contests.covers.com/sportscontests/picksByDate.aspx?date=' . $maand[$i] .'/' . $dag[$i] . '/' . $jaar[$i] .'&ur=' . $expert . '&contestID=15253&sportID=9&t=0';
	
	$array = file($url);
print ($array);

I only get one line instead of 3 which are expected. Can anyone see a mistake in my for loop cause I can't.

I tried your loop and I got three hits. The code I used was:

<?PHP

$maand = array("11","11","11");
$dag = array("2","4","7");
$jaar = array("2007","2007","2007");

$expert = 265839;

for ($i = 0; $i <= 2; $i++){

	$url = 'http://contests.covers.com/sportscontests/picksByDate.aspx?date=' . $maand[$i] .'/' . $dag[$i] . '/' . $jaar[$i] .'&ur=' . $expert . '&contestID=15253&sportID=9&t=0';

	echo "<br><b>Reading $url </b>";
	$array = file($url);    
}

?>

Hi,

I see I made a mistake in my previous post. I also get the url when I ask for it, but I don't get the 2 messages with LOSS, WIN, PUSH.

This is the code with the loop:

<?php


$maand = array("11","11","11");
$dag = array("2","4","7");
$jaar = array("2007","2007","2007");

$expert = 265839;

for ($a=0;$a<=2;$a++){

}

for ($i = 0; $i <= 2; $i++){

			$url = 'http://contests.covers.com/sportscontests/picksByDate.aspx?date=' . $maand[$i] .'/' . $dag[$i] . '/' . $jaar[$i] .'&ur=' . $expert . '&contestID=15253&sportID=9&t=0';

			$array = file($url);

			print($array);

			$key = array_search('		<td><a href="http://www.covers.com/pageLoader/pageLoader.aspx?page=/data/nba/teams/team404169.html">Boston</a></td>
			',$array);

			$arraynba = $key - 1;

			$arraytest = $array[$arraynba];

			if($arraytest == "		<td>NBA</td>
			"){
				$sidepick = $key + 4;
				$totalpick2 = $key + 13;

				$result1 = $array[$sidepick];
				$result2 = $array[$totalpick2];


			} else {
				$sidepick = $key + 4;
				$totalpick2 = $key - 5;

				$result1 = $array[$sidepick];
				$result2 = $array[$totalpick2];
			}

			$datum = $maand[$i] . '/' . $dag[$i] . '/' .$jaar[$i];

			//De gegevens wegschrijven in de database
			print($result1);
			print($result2);
			print($datum);


}

The LOSS, WIN or PUSH are those from the game with BOSTON. As in the example in attachments. I don't understand why I don't get them, I think there is a problem with my $key, because when you ask for $key you don't get any result.

I hope anyone can solve this.

Greets.

Thanks, the script works now:

<?php

			//De gegevens wegschrijven in de database
	print($result1);
	print($result2);
	print($datum);
	print("\r\n");

}
?>

However I stumbled upon another problem. I get the following fatal error:

Fatal error: Maximum execution time of 30 seconds exceeded in C:\Apache\htdocs\test.php on line 18

and line 18 is:

$array = file($url);

Anyone has an idea how to get past this?

Thanks mate, I use the time out limit and it works. You rock m8! When this task is over and don't have any problems any more you definitely get my thanks!

Kligham 0 Light Poster · Answer 6 · 2009-12-17T17:16:06+00:00

Have one little question again:

$array = arrary("WIN", "WIN", "WIN","LOSS","WIN","LOSS","LOSS");

Is there a function that can count all the "LOSS" in the array, so that the answer would be 3?

Only way I know of is array_count_values Notice it returns an array of all the values and their count, not just the one.
