Question

我的数据输出两次，我不知道为什么。它应该是每行一个fname和lname。

<?php

$row = 1;
if (($handle = fopen("nameList1.txt", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, "    ")) !== FALSE) {
        $num = count($data);
        //$result = explode($data);
        echo "<br />\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
                //echo $data[$c];
                echo $data[0];
                echo " ";
                echo $data[1];
        }
    }
    fclose($handle);
}

Answer 1

试试这个

$row = 1;
if (($handle = fopen("nameList1.txt", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, "    ")) !== FALSE) {
    $num = count($data);
    //$result = explode($data);
    echo "<br />\n";
    $row++;
    echo $data[0];
    echo " ";
    echo $data[1];
}
fclose($handle);
}

Answer 2

for ($c=0; $c < $num; $c++) {
    echo $data[0] . " " . $data[1];
}

由于每行有两个不同的数据（fname，lname），$ num总是等于2.

两次，你会打印$ data [0]＆amp; $ data [1];）

你必须这样做：

echo $data[0];
echo $data[0];

或者如果你绝对想要使用for语句：

for ($c=0; $c < $num; $c++) {
    echo $data[$c] . " ";
}

Answer 3

你得到所有csv字段两次因为，while循环中的for循环从0开始，它应该是1到0或

Answer 4

试试这个：

$file = $_FILES[csv][tmp_name]; 
    $handle = fopen($file,"r"); 

    //loop through the csv file and insert into database 
    do { 
        if ($data[0]) { 
            $record['contact_email'] = $data[2];
            $record['subject'] = $_REQUEST['subject'];
            $record['message'] = $_REQUEST['message'];
            $record['status'] = 0;

            $oAdminEmail->insertQueEmail($record);
            } 
    } while ($data = fgetcsv($handle,1000,",","'"));

我从php循环获得双输出
