In Bezug auf diese Frage: Importing CSV data using PHP/MySQL
Die Lösung für Ihr Problem dieses
<?php
$query = <<<eof
LOAD DATA INFILE 'C:/wamp/www/mywebsite/data/m5.csv'
INTO TABLE m4
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(col1,col2,col3,col4,col5)
eof;
$db->query($query);
?>
jedoch sein könnte, wenn Sie in einem PHP-Skript interessiert sind, die das gleiche tut Ding könnte dies versuchen
<?php
$dbhost = "";
$dbname = "";
$dbusername = "";
$dbpassword = "";
$dbtable = "m4";
$fieldseparator = ",";
$lineseparator = "\n";
$csvfile = "C:/wamp/www/mywebsite/data/m5.csv";
/********************************/
/* Set this to 1 if your table have an auto_increment field.
/********************************/
$addauto = 0;
/********************************/
/* Would you like to save the mysqli queries in a file? If yes set $save to 1.
/* Permission on the file should be set to 777. Either upload a sample file through ftp and

/********************************/
$save = 0;
$outputfile = "";
if(!file_exists($csvfile)) {
echo "File not found. Make sure you specified the correct path.\n";
exit;
}
$file = fopen($csvfile,"r");
if(!$file) {

}
$size = filesize($csvfile);
if(!$size) {

$csvcontent = fread($file,$size);
fclose($file);
$conn = mysqli_connect($dbhost, $dbusername, $dbpassword, $dbname) or die('Could not connect');
mysqli_set_charset($conn,"utf8");
$sqldel="DELETE FROM ".$dbtable;
$conn->query($sqldel);
$lines = 0;
$queries = "";
$linearray = array();
foreach(explode($lineseparator,$csvcontent) as $line) {
$lines++;
$line = trim($line," \t");
$line = str_replace("\r","",$line);
/************************************

if($addauto)

else
$query = "INSERT INTO $dbtable VALUES('$linemysql');";
$queries .= $query . "\n";
$res_i=$conn->query($query);
}

Ihre CSV enthält alle Daten Basisdatensätze oder nur die aktualisierten Datensätze? –
Jeden Tag truncate ich meine Tabelle und ich möchte neue Informationen in die mit einer CSV-Datei einfügen – Rocstar
Sind Sie daran interessiert, dies mit einem PHP-Skript und nicht mit PHPMyAdmin-Ereignis zu tun? –
