Question

我正在开发一个网站，允许用户从他们的计算机浏览并选择.csv文件然后该网站将读取.csv文件（以逗号分隔的项目）并将所有项目存储到列表或数组中？之后它将存储到我的数据库中。

我可以知道如何做到这一点？我们非常感谢代码片段和参考资料。

提前致谢！

Answer 1

希望您使用PHP开发您的网站，并希望将用户CSV文件导入MySQL服务器数据库。

您可以使用以下PHP类导入数据： http://www.legend.ws/blog/tips-tricks/csv-php-mysql-import/

假设您已经创建了所需的数据库表。

或者，您可以使用MySQLImport实用程序将任何CSV文件导入MySQL数据库。请参阅http://dev.mysql.com/doc/refman/5.0/en/mysqlimport.html URL以获取有关mySQLImport命令的更多详细信息。

请参阅fgetcsv - http://php.net/manual/en/function.fgetcsv.php，也有一个很好的例子，但我不会先存储在数组中，直接将它们放入数据库中，以便保存ram和额外的循环。

这将上传CSV文件并将数据导入指定的表格。

//Import the contents of a CSV file after uploading it
//http://www.bin-co.com/php/scripts/csv_import_export/
//Aruguments : $table - The name of the table the data must be imported to
//                $fields - An array of fields that will be used
//                $csv_fieldname - The name of the CSV file field
function CSVImport($table, $fields, $csv_fieldname='csv') {
    if(!$_FILES[$csv_fieldname]['name']) return;

    $handle = fopen($_FILES[$csv_fieldname]['tmp_name'],'r');
    if(!$handle) die('Cannot open uploaded file.');

    $row_count = 0;
    $sql_query = "INSERT INTO $table(". implode(',',$fields) .") VALUES(";

    $rows = array();

    //Read the file as csv
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $row_count++;
        foreach($data as $key=>$value) {
            $data[$key] = "'" . addslashes($value) . "'";
        }
        $rows[] = implode(",",$data);
    }
    $sql_query .= implode("),(", $rows);
    $sql_query .= ")";
    fclose($handle);

    if(count($rows)) { //If some recores  were found,
        //Replace these line with what is appropriate for your DB abstraction layer
        mysql_query("TRUNCATE TABLE $table") or die("MySQL Error: " . mysql_error()); //Delete the existing records
        mysql_query($sql_query) or die("MySQL Error: " . mysql_error()); // and insert the new ones.

        print 'Successfully imported '.$row_count.' record(s)';
    } else {
        print 'Cannot import data - no records found.';
    }
}

<强> CSV。从MySQL到'csv'。从'csv'到MySQL 此脚本将表数据转换为“csv”文件。您可以从'csv'文件重新创建表在另一台计算机上。

<?php
// connect to database
require_once '../db_config.php';
$conn = new mysqli ( $dbhost, $dbuser, $dbpass, 'olimrefdb' );
if ($conn->connect_errno) die ( 'no db connection' );   

$tableToConvert = 'mdata';
$csvFileName = $tableToConvert . '_' . date ( "Ymd" );//will contain 'csv' data 

// -----------------------------MySQL table to CSV--------------------------
$tableSchema = $conn->query ( "SHOW CREATE TABLE $tableToConvert" )->fetch_assoc ();
$result = $conn->query ( "SELECT * FROM $tableToConvert" );

$handle = fopen ( $csvFileName.'.csv', 'w' );//to store 'csv' data file
$handle_schema = fopen ( $csvFileName.'_schema.csv', 'w' );//to store table schema 

fputcsv ( $handle_schema, $tableSchema );
while ( $row = $result->fetch_assoc () ) {
    fputcsv ( $handle, $row );
}
fclose ( $handle );
fclose ( $handle_schema );

// -----------------------------CSV to MySQL table--------------------------

$handle = fopen ( $csvFileName.'.csv', 'r' );//open 'csv' data file
$handle_schema = fopen ( $csvFileName.'_schema.csv', 'r' );//open table schema

$tableSchema = fgetcsv ( $handle_schema );
$newTableName = "$tableSchema[0]_" . date ( "Ymd" );

// change table name in schema
$tableSchema [1] = preg_replace ( "/$tableSchema[0]/", $newTableName, $tableSchema [1], 1 );

$conn->query ( "DROP TABLE IF EXISTS $newTableName" );
$conn->query ( $tableSchema [1] );//CREATE TABLE 
//  $conn->query ( "CREATE TABLE $newTableName LIKE $tableToConvert");//the same, but without using schema

while ( $row = fgetcsv ( $handle ) ) {
    $data = implode ( "','", $row ); //convert array to string

    if ($conn->query ( "INSERT INTO $newTableName values('$data')" )) {
    } else {
        echo '<span style="color:red">Problem:</span> ' . $data . '<br>';
        var_dump ( $conn->error_list );
        fclose ( $handle );
        exit ();
    }
}

fclose ( $handle ); 
echo 'Congratulation!!!' . '<br>';
