PHP MySQL更新记录

PHPmysql_query()函数用于更新表中的记录。从PHP5.5开始，不推荐使用mysql_query()函数。现在建议使用两种替代方法之一。

• mysqli_query()
• PDO :: __ query()

PHP MySQLi更新记录示例

<?php
$host = 'localhost:3306';
$user = '';
$pass = '';
$dbname = 'test';

$conn = mysqli_connect($host, $user, $pass,$dbname);
if(!$conn){
  die('Could not connect: '.mysqli_connect_error());
}
echo 'Connected successfully<br/>';

$id=2;
$name="Rahul";
$salary=80000;
$sql = "update emp4 set name="$name", salary=$salary where id=$id";
if(mysqli_query($conn, $sql)){
 echo "Record updated successfully";
}else{
echo "Could not update record: ". mysqli_error($conn);
}

mysqli_close($conn);
?>

输出：

Connected successfully
Record updated successfully
