PHP MySQL刪除數據記錄
PHP mysql_query()
函數用於刪除表中的數據記錄。 由於PHP 5.5版本起,不推薦使用mysql_query()
函數。 現在,建議使用2種替代方法之一。
- mysqli_query()
- PDO::__query()
PHP MySQLi刪除數據記錄示例
示例
<?php
$host = 'localhost:3306';
$user = 'root'; // MySQL用戶賬號
$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;
$sql = "delete from emp4 where id=$id";
if(mysqli_query($conn, $sql)){
echo "Record deleted successfully";
}else{
echo "Could not deleted record: ". mysqli_error($conn);
}
mysqli_close($conn);
?>
執行上面示例代碼,得到以下結果 -
Connected successfully
Record deleted successfully
