Lost in iterating through scraped data.

[Godfrey]

I'm trying to get back into PHP, but I'm running into some trouble. I'm creating a little script that scraps data from a page and then displays it elsewhere. (I'm actually going to insert it into a database, but for now, just trying to display it! There's two pages I'm scraping from.

 

This scrapes the list of players from one web page:

$html = file_get_contents("http://www.somesite.com/players.php?search=who");

preg_match_all(
    '/<td width=\'33\.3333333333\%\'><a href=\'\/players.php\?lookup=.*?\'>(.*?)<\/a>/',
    $html,
    $players,
    PREG_SET_ORDER
);

That matches fine. Then for each name I want to scrape another page that has more information about each individual player:

foreach ($players as $player) {

$html2 = file_get_contents("http://www.somesite.com/players.php?lookup=$player");

preg_match_all(
    '/<font size=\'\+1\'><strong>.*?<\/font><\/strong>/',
    $html2,
    $longName,
PREG_SET_ORDER
);
preg_match_all(
    '/Race<\/font><\/td><td><font size=\'\-1\'>.*?<\/font>/',
    $html2,
    $race,
PREG_SET_ORDER
);
preg_match_all(
    '/Citizenship<\/font><\/td><td><font size=\'\-1\'>.*?<\/font>/',
    $html2,
    $citizenship,
PREG_SET_ORDER
);
preg_match_all(
    '/Level<\/font><\/td><td><font size=\'\-1\'>.*?<\/font>/',
    $html2,
    $level,
PREG_SET_ORDER
);

echo $longName[0][0];
echo ("<br>");
$rac = implode("", $race[0]);
$newrace = substr($rac, 4, -1);
echo $newrace;
echo ("<br>");
$cit = implode("", $citizenship[0]);
$newcit = substr($cit, 11, -1);
echo $newcit;
echo ("<br>");
$lev = implode("", $level[0]);
$newlevel = substr($lev, 5, -1);
echo $newlevel;
echo ("<br>");

}

This does not work. I get Warning: implode() [function.implode]: Invalid arguments passed in /my/path/names.php on line <three implode lines> and I get NO echos except for the break lines. HOWEVER, if I just use this code outside of a loop, i.e. I just do $html2 = file_get_contents("http://www.somesite.com/players.php?lookup=MyPlayerName"); it works perfectly.

 

I'm newb at coding, so I can't even figure out what data it is or is not getting in the iteration, and why it's not displaying/getting it when it's looped through each name as opposed to when it works perfectly when I input a single name in the file_get_contents. Can anyone see errors in how I'm going about this or suggest some checks to put in to help figure out what the heck is going wrong?

 

Thanks much for any help.

try to change

foreach ($players as $player) {

to

foreach ($players[1] as $player) {

I ended up scraping just the names in another way, and the other data in the same way, and that worked. So thanks.
