PHP mysqli_insert_id() 函数

实例

假设 Persons 表有一个自动生成的 ID 字段。返回最后一次查询中的 ID：

 <?php
 $con=mysqli_connect("localhost","my_user","my_password","my_db");
 // Check connection
 if (mysqli_connect_errno($con))
 {
 echo "Failed to connect to MySQL: " . mysqli_connect_error();
 }

mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age) 
 VALUES ('Glenn','Quagmire',33)");

// Print auto-generated id
echo "New record has id: " . mysqli_insert_id($con); 

mysqli_close($con);
 ?>
