I am learning the PHP programming using Larry Ullman's book "PHP Advanced for the World Wide Web". After successfully going through a few scripts one script kept producing error message whenever I ran it. The script is provided herebelow: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/2000/REC-xhtml1-20000126/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <title>Football Picks</title> </head> <body> <?php # Script 1.11 /* ------------------------------- */ /* Calculate the season standings. */ /* ------------------------------- */ function do_the_math ($value, $key, $total) { // This function adds up the wins and losses. if ($key != 0) { // Ignore the first dummy line. $line = explode ("\t", $value); // Separate out the username, wins, and losses. $_REQUEST['username'] = $line[0]; $total["{$_REQUEST['username']}"]["wins"] += $line[1]; $total["{$_REQUEST['username']}"]["losses"] += $line[2]; } } function read_results ($dp, $directory, &$total) { if ($file_name = readdir ($dp)) { // Search through the directory. if (substr($file_name, 0, 8) == "results_") { // If it's a results file ... $the_file = $directory . $file_name; array_walk (file ($the_file), 'do_the_math', &$total); // Do the math on all the data. } read_results ($dp, $directory, $total); // Repeat through the directory. } } $total = array(); // Initialize the main variable. $directory = '2001/'; $dp = opendir ($directory); read_results ($dp, $directory, $total); // Start the process. closedir ($dp); echo "<pre>\n"; var_dump ($total); // Quickly print out the results. echo "</pre>\n"; ?> </body> </html> The error message is: "PHP - This program has performe an illegal operation and will be shut down....."
