Question

我试图通过php将数据从xls导入到mysql。我正面临通过它保存UTF-8文本的问题。我把它保存为 ???????。我的数据库表结构是utf8_general_ci以及我的php代码如下所示

 <?php 
    $con = mysqli_connect('localhost', 'myuser', 'mypass', 'mydb');


    if(isset($_POST["submit"]))
    {
    mysqli_query($con,'SET character_set_results=utf8');
    mysqli_query($con,'SET names=utf8');
    mysqli_query($con,'SET character_set_client=utf8');
    mysqli_query($con,'SET character_set_connection=utf8');
    mysqli_query($con,'SET character_set_results=utf8');
    mysqli_query($con,'SET collation_connection=utf8_general_ci');
    $file = $_FILES['file']['tmp_name'];
    $handle = fopen($file, "r");
    $i = 0;
    while(($filesop = fgetcsv($handle, 1000, ",")) !== false)
    {	
    $option1 = $filesop[0];
    $option2 = $filesop[1];
    $option3 = $filesop[2];
    $option4 = $filesop[3];
    $correctans = $filesop[4];
    $question_text = $filesop[5];
    $cat_id = $filesop[6];
    $sub_cat_id = $filesop[7];
    $level_id = $filesop[8];
    $quesimage = $filesop[9];

    $sql = mysqli_query($con,"INSERT IGNORE INTO questions (option1, option2,option3,option4,correctans,question_text,cat_id,sub_cat_id,level_id,quesimage) VALUES ('".$option1."','".$option2."','".$option3."','".$option4."','".$correctans."','".$question_text."','".$cat_id."','".$sub_cat_id."','".$level_id."','".$quesimage."')");
    $i = $i + 1;
    	
    }
    //echo $sql;
    if($sql)
    {
    echo "You database has imported successfully. You have inserted ". $i ." records";
    }
    else
    {
    echo "Sorry!";
    }

    }
     
    ?>

它与英文文本一起工作正常，但在印地语或古吉拉特语文本中出现问题。我该如何解决？

请注意，使用fgetcsv()功能读取数据时，会考虑locale设置。如果是LANG，例如en_US.UTF-8，此函数读取单字节编码的文件错误。

您可以尝试其他方法 - 即时转换.csv文档（使用您的文件编码更改UCS-2）：

function parse_csv($filename) {
    if (($handle != fopen($filename, "r"))) return false;
    while (($cols = fgetcsv($handle, 1000, "\t")) !== FALSE) {
        foreach( $cols as $key => $value ) {
            $cols[$key] = trim( $cols[$key] );
            $cols[$key] = iconv('UCS-2', 'UTF-8', $cols[$key]."\0") ;
            $cols[$key] = str_replace('""', '"', $cols[$key]);
            $cols[$key] = preg_replace("/^\"(.*)\"$/sim", "$1", $cols[$key]);
        }
        echo var_dump($cols); //This will display an array of your data
    }
}

使用与上一篇文章相同的想法，稍作修改：

function global_client_charset($charset){
if(!isset($charset)){
    $user_agent = strtolower($_SERVER['HTTP_USER_AGENT']);
    if(strrpos($user_agent,"linux")){
    $GLOBALS["CHARSET"] = "UTF-8";
    }else if(strrpos($user_agent,"windows")){
    $GLOBALS["CHARSET"] = "ISO-8859-1";
    }
}else{
        $GLOBALS["CHARSET"] = $charset;
}       
}

function toUTF8($data){
    if($GLOBALS["CHARSET"] === "ISO-8859-1"){
        return iconv("ISO-8859-1", "UTF-8", trim($data));
    }else if($GLOBALS["CHARSET"] === "UTF-8"){
       return trim($data);
    }else{
       return trim($data);
    }
}

if(isset($_POST["submit"]))
{
$file = $_FILES['file']['tmp_name'];
$handle = fopen($file, "r");
$i = 0;

//do you know the charset you are receiving ??
//global_client_charset("ISO-8859-1");
global_client_charset();

while(($filesop = fgetcsv($handle, 1000, ",")) !== false)
{   
    $option1 = $filesop[0];
    $option2 = $filesop[1];
    $option3 = $filesop[2];
    $option4 = $filesop[3];
    $correctans = $filesop[4];
    $question_text = $filesop[5];
    $cat_id = $filesop[6];
    $sub_cat_id = $filesop[7];
    $level_id = $filesop[8];
    $quesimage = $filesop[9];


    $query = "INSERT IGNORE INTO questions (option1, option2,option3,option4,correctans,question_text,cat_id,sub_cat_id,level_id,quesimage) VALUES ('".
    $option1."','".$option2."','".$option3."','".$option4."','".$correctans."','".$question_text."','".
    $cat_id."','".$sub_cat_id."','".$level_id."','".$quesimage."')"; 

    //echo toUTF8($query); die();
    $sql = mysqli_query($con,toUTF8($query));
    $i = $i + 1;        
}

if($sql)
{
    echo "You database has imported successfully. You have inserted ". $i ." records";
}
else
{
    echo "Sorry!";
}
}
