PHP MySQL删除记录

PHP mysql_query()函数用于删除表中的记录。从PHP 5.5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()

if(!$conn){
  die('Could not connect: '.mysqli_connect_error());
}
echo 'Connected successfully<br/>';

$id=2;
$sql = "delete from emp4 where id=$id";
if(mysqli_query($conn, $sql)){
 echo "Record deleted successfully";
}else{
echo "Could not deleted record: ". mysqli_error($conn);
}

mysqli_close($conn);
?>
