Pdo按編號插入多行

Question

我沒有什么問題，我不知道如何使它工作。 我想進行按編號插入行的查詢。 示例：如果發布的數字為8，則查詢將添加8行。

知道如何用pdo做到這一點？

SQL

INSERT INTO
    foo(bar,baz)
VALUES
    ("val1", "val2"),
    ("val1", "val2"),
    ("val1", "val2"),
    ("val1", "val2"),
    ("val1", "val2"),
    ("val1", "val2"),
    ("val1", "val2"),
    ("val1", "val2")
;

PHP

//Insert Statement
$sql = 'INSERT INTO foo(bar,baz) VALUES ';

//Values ("val1", "val2"),("val1", "val2"),("val1", "val2"),..
for ($i = 0; $i <= 8; $i++) {
    $sql.= '("val1", "val2"),';
}

//Remove last Comma, and set ";" at the end.
$sql = rtrim($sql, ",") . ';';
