PHP while循環不起作用

Question

我不明白為什么插入第一行數據后我的while循環停止。 請幫忙。 我正在嘗試在MySql表中上載.csv文件-如果數據已經存在，請跳過並轉到第二行。

<?php
$dbhost = "xxxx";
$dbname = "xxxx";
$dbuser = "xxxx";
$dbpass = "xxxx";
mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error());
mysql_select_db($dbname) or die(mysql_error());

fgetcsv_PHP();

function fgetcsv_PHP()
{

    if (($handle = fopen("events.csv", "r")) !== FALSE)
    {

        $length = 1000;
        $delimiter = ",";



        while ( ( $data = fgetcsv( $handle) ) !== FALSE )
        {
            // Count number of array elements in $data
            $num = count($data);
            // Print opening table row HTML tag
            $data[5]= strtolower($data[5]);
            $data[11]= "2012-06-22 10:30:40";
            $import="INSERT into candidatedb(event,rec,title,name,surname,email,phone,discip,exper,wheread,comment,stamp) values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]','$data[9]','$data[10]','$data[11]')";


            $result = mysql_query("SELECT * from candidatedb WHERE email = '$data[5]' AND surname = '$data[4]'");
            $num_rows = mysql_num_rows ($result);
            echo $num_rows;

            if ($num_rows > 0) {

                echo "Email address: $data[5] already exist </br>"; 
            }

            else {      

                    mysql_query($import) or die(mysql_error());
                    echo "Done! $data[5] inserted<br/>";
            }
        }
        // Close the file pointed to by $handle
        fclose($handle);
    }
}

"Done!<br/> $num record uploaded" 
?>




<?php /*?>
       $import="INSERT into candidatedb(event,rec,title,name,surname,email,phone,discip,exper,wheread,comment,stamp) values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]','$data[9]','$data[10]','$data[11]')";

       mysql_query($import) or die(mysql_error());
<?php */?>

如果嘗試使用此命令進行調試，輸出結果如何：

fgetcsv_PHP();

function fgetcsv_PHP() {

$length    = 1000;
$delimiter = ",";
if (($handle = fopen("events.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, $length, $delimiter)) !== FALSE)
    {
        echo "read line: ".implode($data, ';')." <br>\n";
    }
    fclose($handle);
}
}

好的，我發現了問題。 它不是.csv文件的代碼。 由於某些原因，PHP函數無法正確解碼Mac版Excel的.csv版本“逗號分隔值”。 但是，如果將.csv導出為“ Windows逗號分隔（.csv）”，則它就像一個超級按鈕一樣起作用。

謝謝你的幫助。
