Question

我有以下代码将csv文件上传到mysql数据库。它工作正常，但如果csv文件包含每列的标题，它将上传到表的第一行。我想在存储到数据库中时删除csv文件的第一行。我怎么能这样做？

<?php  

    //connect to the database 
    $connect = mysql_connect("localhost","root",""); 
    mysql_select_db("crm",$connect); //select the table 
    // 

    if ($_FILES[csv][size] > 0) { 

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

        //loop through the csv file and insert into database 
        do { 
            if ($data[0]) { 
                mysql_query("INSERT INTO lead (name, lead_value, status) VALUES 
                    ( 
                        '".addslashes($data[0])."', 
                        '".addslashes($data[1])."', 
                        '".addslashes($data[2])."' 
                    ) 
                "); 
            } 
        } while ($data = fgetcsv($handle,1000,",","'")); 
        // 

        //redirect 
        header('Location: import.php?success=1'); die; 

    } 

    ?>

我正在使用的示例代码，它应该可以工作，因为我在生产环境中使用它

$handle = fopen("stuff.csv","r");

/* assuming that first row has collumns names */
$query = "INSERT INTO table(";
$cols = fgetcsv($handle,100000,';','"');
$query .= implode(", ",$cols).") VALUES";

$values = "";

    /* cycle through each row and build mysql insert query */
while($data = fgetcsv($handle,100000,';','"')) {
    $values .= " ( ";

    foreach($data as $text) {

        $values .= "'".$text."', ";

    }

    $values = substr($values,0,-2);

    $values .= "), ";

}

    /* remove last 2 chars */

$values = substr($values,0,-2);

$query .= $values;

echo $query;

fclose($handle);

请注意，此脚本将返回mysql查询...不执行它，因此请根据需要进行更改。

我认为您的意思是您不希望将CSV数据的第一行行插入到表格中。在这个假设上工作（注意我不是PHP程序员，因此我所做的更改应该被视为伪代码）：

if ($_FILES[csv][size] > 0) { 
    $first_time = true;

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

    //loop through the csv file and insert into database 
    do {
            if ($first_time == true) {
            $first_time = false;
            continue;
        }

        if ($data[0]) { 
            mysql_query("INSERT INTO lead (name, lead_value, status) VALUES 
                ( 
                    '".addslashes($data[0])."', 
                    '".addslashes($data[1])."', 
                    '".addslashes($data[2])."' 
                ) 
            "); 
        } 
    } while ($data = fgetcsv($handle,1000,",","'")); 

    //redirect 
    header('Location: import.php?success=1'); die; 
}

如果我理解正确你想要删除标题行？我会使用LOAD DATA代替INSERT INTO

LOAD DATA INFILE '/tmp/test.csv' INTO TABLE test FIELDS TERMINATED BY ',' IGNORE 1 LINES;

LOAD DATA在性能方面远优于INSERT。

MySQL - LOAD DATA

删除csv文件中的第一行上传到mysql数据库
