Php 我试图在pdo中使用multi-query插入两个表，但它给出了一个致命错误：未捕获错误：调用未定义的方法pdo:：multi_-query（）

当我尝试使用multi-query插入时，它会给出错误，但是如果没有multi-query，它只插入第一个表，而第二个表不会得到任何数据

$db = new PDO('mysql:host='.$db_host.';dbname='.$db_database, $db_user, $db_pass);

multi_query

和

next_result

是MySQLi中的函数，而不是PDO

改变

$sql = "INSERT INTO solditem (invoice,id_ya_dawa,name,package,re_id,customer,CreatedBy,insurance,strengthtype,dosage,age,ItemCode,UnitPrice,ApprovalRefNo,DateCreated) VALUES (:a,:b,:e,:i,:w,:x,:u,:t,:s,:n,:v,:p,:r,:l,NOW());";
$sql .= "INSERT INTO anotheritem (DateCreated,CreatedBy,UnitPrice,LastModified,LastModifiedBy,ItemName,ItemCode,ApprovalRefNo,re_id) VALUES (NOW(),:w,:u,:p,NOW(),:w,:e,:v,:r,:l)";
$q =$db -> multi_query($sql);
$q =$db -> next_result();
$q->execute (array(':a'=>$a,':b'=>$b,':e'=>$gen,':i'=>$code,':w'=>$w,':x'=>$x,':u'=>$u,':t'=>$t,':s'=>$s,':n'=>$n,':v'=>$age,':p'=>$asasa,':r'=>$code,':l'=>$l));
