php - C 中给出的警告 : fgetcsv() expects parameter 1 to be resource, bool 值:

Question

我正在尝试使用 fgetcsv() 获取 CSV，但出现如下错误:

Warning: fgetcsv() expects parameter 1 to be resource, boolean given in C:..

如果我 var_dump($handle) 确保输出是:Bool(False)

<?php

    $handle = fopen($_FILES['filename']['tmp_name'], "r");
    //var_dump($handle);die;
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        //print_r ($data);die;
        $import="INSERT into pickup_28(NO,TGL_PICKUP,SERVICE_NUMBER,ICCID,CUSTOMER_NAME,PRODUCT,ALAMAT,NO_ALT,AREA) 
        values('$data[0]','$data[1]','$data[2]','$data[3]','$data[4]','$data[5]','$data[6]','$data[7]','$data[8]')";

        mysql_query($import) or die(mysql_error());

    }

?>

在尝试使用结果之前需要测试fopen是否成功:

$handle = fopen($_FILES['filename']['tmp_name'], "r");
if ($handle) {
    // Use $handle
} else {
    die("Unable to open file");
}
