Question

我试图在使用php + mysql插入后立即获取插入行的内容。在php + mysql中是否有任何方法可以立即获取插入的行（所有列）。

我是php + mysql的新手。

Answer 1

试试这个：

<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
  {
  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);
?>

Answer 2

插入行后获取插入的行。下面的例子使用php prepared语句方法插入和从数据库表中获取数据。

对于数据库连接，您必须创建php代码。

数据库连接

$servername = "your server name";
  $username = "your username";
$password = "your password";
$db = "your database name";

$conn = new mysqli($servername, $username, $password, $db);

 // Check connection
 if ($conn->connect_error) {
  die("Connection failed: try again after some time ");
   }


$insert_stmt = $conn->prepare("INSERT INTO log (username, email, password)   
  VALUES (?, ?, ?)")); 
$insert_stmt->bind_param('sss', $username, $email, $password);
$insert_stmt->execute();

执行此操作后，您可以立即查询同一个表并获取该行。像这样 -

$prep_stmt = "SELECT * FROM log WHERE username = ? LIMIT 1";
$stmt = $conn->prepare($prep_stmt);
 $stmt->bind_param('s', the username you just inserted);
    $stmt->execute();
 $stmt->bind_result($the variable names in which you want to bind the      
 results separated by commas);
        $stmt->fetch();

如果插入了数据，则可以获取。

Answer 3

您可以通过内置的php函数mysql_insert_id();

获取最新插入的行ID

$id = mysql_insert_id();

你也可以通过

获得最新的行ID

$id = last_insert_id();

Answer 4

如果数据被插入成功返回应该是一个新的id
