检索自动增量数据库值

Question

我需要检索自动增量值并在执行插入查询后将其存储在会话中。

我的表名是4个字段ID（主键和自动增量），名称，电话，电子邮件。

$query = mysql_query($con, "insert into out(name, phone, email) values ('$name', '$phone', '$email')");                                                                            
$id = mysql_insert_id($con);                                                                               
while($rowval = mysql_fetch_array($query))
{ 
 $id= $rowval['id']; 
 }
if($query)
{ 
  $_SESSION['id'] = $id; 
}

Answer 1

  try this.
$sql = mysql_query($con, "INSERT INTO(col1, col2, col3) values (val1, val2, val3)";
$mysql->query($sql); 
$last_inserted_id=$mysql->insert_id; // returns last ID


//you can get last inserted id then set it in session. 

Answer 2

获取最后一个插入ID的最通用方法是简单地选择它。

$result = mysql_query("SELECT LAST_INSERT_ID()");
$lastId = mysql_result($result, 0, 0);

Answer 3

$query = mysql_query($con, "insert into out(name, phone, email) values ('$name', '$phone', '$email')");                                                                            
$id = mysql_insert_id(); 

  

//只需删除$ con ...

while($rowval = mysql_fetch_array($query))
{ 
 $id= $rowval['id']; 
 }
if($query)
{ 
  $_SESSION['id'] = $id; 
}
