Pdo按编号插入多行

Question

我有一点小问题，我不知道如何使它工作。 我想通过编号插入行的查询。 示例： 如果发布号码是8，则查询会添加8行。

任何想法如何用pdo做到这一点？

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, ",") . ';';
