我正在从php循环中获取双输出

Question

My data is outputting twice and I am not to sure why. It should be one fname and lname per line.

<?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);
}

** * ** output ** * ** * ** * **

Answer 1

try this

$row = 1;
if (($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];
}

As you have 2 differents data per line (fname, lname) $num is always equal to 2.

So twice, you will print out $data[0] & $data[1] ;)

You juste have to do :

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

Or if you absolutely want to use the for statement :

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

Answer 3

您将两次获取所有csv字段，因为，while循环内的forloop从0到开始，应为1或0到

Answer 4

try this:

$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,",","'"));
