检查什么类型的.csv应该导入到mysql中

Question

我有两种类型的.csv，一种以“，”结尾，一种以“;”结尾

如何设置php以选择要导入的csv文件？ （.csv名称是动态的）

foreach (glob("*.csv") as $filename) {
$csvfile = ($filename);
}

我的PHP代码：

$affectedRows = $pdo->exec( 
"LOAD DATA LOCAL INFILE '$filename' 
INTO TABLE $databasetable 
FIELDS TERMINATED BY ';' 
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(@dummy, name, data, value)");

$affectedRows = $pdo->exec( 
"LOAD DATA LOCAL INFILE '$filename' 
INTO TABLE $databasetable 
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(name, data)");
