我在mysql中创建了一个程序
DELIMITER //
create procedure insert_trans_id (IN $Project_Code varchar(100),IN $user_name
varchar(100),IN $item_name varchar(100),IN $Unit_Name
varchar(100),IN $item_size1 varchar(50),IN $item_qty1 int,IN $l_name varchar(100)
)
begin
//variable declare here
declare $p_id int;
declare $user_id int;
declare $i_id int;
declare $unit_id int;
declare $item_size varchar(50);
declare $item_qty int;
declare $loc_id int;
//setting variables
set @item_size = ($item_size1);
set @item_qty = ($item_qty1);
set @p_id = (SELECT `id` FROM `project_master` WHERE `Project_Code` `enter code here`= $Project_Code) ;
set @user_id = ( SELECT `u_id` FROM `user` WHERE `user_name` = $user_name);
set @i_id =(SELECT `id` FROM `item_master` WHERE `item_name` = $item_name);
set @unit_id = (SELECT `id` FROM `unit_mstr` WHERE `Unit_Name` = $Unit_Name);
set @loc_id = (SELECT `id` FROM `location_mstr` WHERE `l_name` = $l_name);
PREPARE STMT FROM
// insert statement
"INSERT INTO `project_transaction_header`(`project_id`, `u_id`, `item_Id`,`unit_id`,`Size`, `Qty`, `location_id`, `Created_On`, `Created_By`,`Modified_on`, `Modified_By`)VALUES(p_id,user_id,i_id,$unit_id,item_size,item_qty,loc_id,'system',now(),'system',now() )";
EXECUTE STMT USING @p_id,@user_id,@i_id,@$unit_id,@item_size,@item_qty,@loc_id;
END
它在 mysql phpmyadmin 中工作正常，但我现在不知道如何在 php 中调用相同的过程，如果可能需要示例，请帮助我
