Вы можете реализовать интерфейс для выбора таблиц, которые вы хотите импортировать в прямом эфире. Используйте приведенный ниже код для создания CSV-файлов выбранных таблиц и подготовки массива.
<?php
$file_name_flat = 'TABLE-NAME.csv'; // Replace TABLE-NAME with your selected table name.
$fpointer = fopen(FOLDER-LOCATION.$file_name_flat, 'w+'); // Open CSV file. Replace
FOLDER-LOCATION with your local folder path where you want to save this CSV files.
//Execute query to get all columns data
$query = "select * FROM TABLE-NAME WHERE 1"; // Replace TABLE-NAME with your selected
table name. You can set other conditions based on your requirement.
//Execute query as per your CMS / Framework coding standards and write CSV file.
$result_flat = $DB_Connection->query($query)->fetchAll('assoc');
foreach ($result_flat as $fields) {
fputcsv($fpointer, $fields);
}
//Prepare Array of CSVs to create ZIP file
$files = array($file_name_flat);
fclose($fpointer); // close CSV file after successfully write.
?>
СОЗДАТЬ ЗИП CSV
//Create ZIP
$zipname = 'tables_'.date('Y-m-d-H-i-s').'.zip';
createZipFile($files,$zipname,FOLDER_LOCATION); //Replace FOLDER-LOCATION with your
local folder path where you saved CSV files.
/* createZipFile Funcation to create zip file Both params are mandatory */
function createZipFile($files_names = array(),$zipfileName, $files_path=""){
$zip = new \ZipArchive;
$zip->open(TMP.$zipfileName, \ZipArchive::CREATE);
foreach ($files_names as $file) {
$zip->addFile($files_path.$file,$file);
}
$zip->close();
foreach ($files_names as $file) {
unlink($files_path.$file);
}
///Then download the zipped file.
header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$zipfileName);
header('Content-Length: ' . filesize(FOLDER_LOCATION.$zipfileName));
readfile(TMP.$zipfileName);
unlink(TMP.$zipfileName);
die;
}
Теперь реализуйте форму для загрузки этого zip-файла на работающий сервер. В поле Действия этой формы добавьте код для получения zip-файла.
$filename = $_FILES['filename']['name'];
$source = $_FILES["filename"]["tmp_name"];
//Upload zip file to server location. Replace SERVER_FOLDER_PATH to server's location
where you want to save uploaded zip.
if(move_uploaded_file($source, SERVER_FOLDER_PATH)) {
//Extract ZIP file
$zip = new \ZipArchive();
$x = $zip->open($target_path);
if($x === true) {
$zip->extractTo(PATH_TO_SAVE_EXTRACTED_ZIP); // change this to the correct site path
$zip->close();
$cdir = scandir(PATH_TO_SAVE_EXTRACTED_ZIP); // Read DIR
$fieldSeparator = ",";
$lineSeparator = '\n';
foreach ($cdir as $key => $value)
{
if (!in_array($value,array(".","..")))
{
$fileName = PATH_TO_SAVE_EXTRACTED_ZIP.$value; // replace
PATH_TO_SAVE_EXTRACTED_ZIP with your server path
$tableName = SET_TABLE_NAME; // You have to set the logic to get the table name.
if (is_file($fileName))
{
// User MYSQL "LOAD DATA LOCAL INFILE" to IMPORT CSVs into particular tables. There are option available for this LOAD DATA process. It will import your CSV to particular table. No need to execute loop to insert data one by one.
$q = 'LOAD DATA LOCAL INFILE "'.$fileName.'" REPLACE INTO TABLE '.$tableName.' FIELDS TERMINATED BY "' .$fieldSeparator. '" Enclosed BY '.'\'"\''.' LINES TERMINATED BY "'.$lineSeparator.'"';
$DB_Connection->query($q);
}
}
}
}
