foreach usage

[Zugzwangle]

Hi.

 

I have a simple question about using foreach statements.  I have data posted from a form, which is in the following format:

[Event "Rated game, 90m + 5s"]
[site "Room 1"]
[Date "2010.07.05"]
[Round "?"]
[White "Jugarul"]
[black "Zeroonze"]
[Result "0-1"]
[ECO "C00"]
[WhiteElo "1953"]
[blackElo "2052"]
[PlyCount "84"]
[EventDate "2010.07.05"]
[TimeControl "5400+5"]

1. e4 {4} e6 {1} 2. d3 {7} d5 {15} 3. Nd2 {2} Nf6 {3} 4. g3 {15} Nc6 {217} 5.
Bg2 {11} dxe4 {11} 6. dxe4 {15} e5 {11} 7. Ngf3 {50} Bc5 {28} 8. O-O {42} O-O {
3} 9. h3 {295 Jugarul offers a draw} Qe7 {211} 10. c3 {7} a5 {147} 11. a4 {5}
b6 {343} 12. Re1 {185} Ba6 {20} 13. Qb3 {1022} Bd3 {710} 14. Nh4 {64} g6 {211}
15. Nf1 {220} Rfe8 {940} 16. Be3 {101} Kg7 {91} 17. Rad1 {324} Rad8 {96} 18.

{2} Ra1+ {2 Jugarul resigns  (Lag: Av=1.67s, max=3.1s)} 0-1

I have created some code to sort this data, by the constants from the data recieved - for example "[site " will always -> Room 1.

Here is my code:

<?php

{
function main_main()
{
	echo ""; 


	global $dbhost, $dbname, $dbuser, $dbpasswd;
	$link = mysql_connect($dbhost, $dbuser, $dbpasswd)
		or die('Could not connect: ' . mysql_error());
		mysql_select_db($dbname) or die('Could not select database');


	$textData = $_POST["myTextArea"];
	//$textData = $pgn;

	$partsTop = str_replace('[', "", $textData);
	$partsTop2 = str_replace('\"', "", $partsTop);

	$parts = explode("]", $partsTop2);
	$numberOf = count($parts);

	foreach($parts as $val) 
	{
		$whiteNo = strstr($val, 'White ');
		$blackNo = strstr($val, 'Black ');
		$controlNo = strstr($val, 'Event ');
		$locationNo = strstr($val, 'Site ');
		$dateNo = strstr($val, 'EventDate ');
		$resultNo = strstr($val, 'Result ');
		$notation = strstr($val, '1. ');

		$white = str_replace('White ', "", $whiteNo);
		$black = str_replace('Black ', "", $blackNo);
		$control = str_replace('Event ', "", $controlNo);
		$location = str_replace('Site ', "", $locationNo);
		$date = str_replace('EventDate ', "", $dateNo);
		$result = str_replace('Result ', "", $resultNo);

		echo $white;
	}
	echo $white;	

}
}
?>

The above, within the foreach statement, the variables I desire, for example $white = Jugarul, $black = Zeroonze, etc, to later be manipulated. 

 

However, the "echo $white;" within the 'foreach' statement works fine on all of the variables I need, but the "echo $white;" statement outside the 'foreach' returns with nothing.  What am I misunderstanding about foreach statements?

It seems to me that using regular expression for this might be more straightforward.

each iteration of the foreach loop overwrites the previous value of $white (and the other variables) with a new value... if you are wanting to save the data from each iteration, store it in an array:

 

$white[] = str_replace('White ', "", $whiteNo);

 

then for instance you can access the value of the first iteration with $white[0], 2nd iteration with $white[1], etc...

Thanks!!

You can reduce the following code

		$partsTop = str_replace('[', "", $textData);
	$partsTop2 = str_replace('\"', "", $partsTop);

	$parts = explode("]", $partsTop2);
	$numberOf = count($parts);

	foreach($parts as $val) 
	{
		$whiteNo = strstr($val, 'White ');
		$blackNo = strstr($val, 'Black ');
		$controlNo = strstr($val, 'Event ');
		$locationNo = strstr($val, 'Site ');
		$dateNo = strstr($val, 'EventDate ');
		$resultNo = strstr($val, 'Result ');
		$notation = strstr($val, '1. ');

		$white = str_replace('White ', "", $whiteNo);
		$black = str_replace('Black ', "", $blackNo);
		$control = str_replace('Event ', "", $controlNo);
		$location = str_replace('Site ', "", $locationNo);
		$date = str_replace('EventDate ', "", $dateNo);
		$result = str_replace('Result ', "", $resultNo);

		echo $white;
	}

down to just

preg_match_all('/\[(.*)\]/', $textData, $matches);

$vars = array();
foreach($matches[1] as $value)
{
   list($key, $data) = explode(' "', $value);
   
   $var[$key] = trim($data, '"');
}

echo $var['White'];
