Question

我是PHP的初学者，我无法解决此错误，感谢您的回答。它是一个简单的连接到MySQL中的数据库的列：

Name
Last Name
Email

解析错误：

语法错误，意外的'“”'（T_CONSTANT_ENCAPSED_STRING），在第7行的C：\ xampp \ htdocs \ Suscribe \ registro.php中期待变量（T_VARIABLE）或'{'或'$'

$db_host="localhost";
$db_user="root";
$db_password="";
$db_name="prueba";
$db_table_name="datos";
   $db_connection = mysql_connect("$localhost", "$root","");

    die('No se ha podido conectar a la base de datos');
}
$Nombre = utf8_decode($_POST['nombre']);
$Apellido = utf8_decode($_POST['apellido']);
$Email = utf8_decode($_POST['email']);

    header('Location: Fail.html');
}else{
    $insert_value = 'INSERT INTO `' . $prueba. '`.`'.$datos.'` (`nombre` , `apellido` , `email`) VALUES 
    ("' . $Nombre . '", "' . $Apellido . '", "' . $Email . '")';
    mysql_select_db($prueba, $db_connection);

        die('Error: ' . mysql_error());
    }
    header('Location: Success.html');
}
mysql_close($db_connection);

Answer 1

mysql已弃用，您应使用mysqli或pdo

更改

$db_connection = mysql_connect("$localhost", "$root","");

要

$db_connection = mysql_connect($localhost, $root,"");

还有一件事你没有连接DB

你应该写

mysql_select_db($db_name);

在mysql_connect之后

Answer 2

试试这个

<?php 

$db_host="localhost";
$db_user="root";
$db_password="";
$db_name="prueba";
$db_table_name="datos";
   $db_connection = mysql_connect($db_host, $db_user,$db_password);

if (!$db_connection) {
    die('No se ha podido conectar a la base de datos');
}
$Nombre = utf8_decode($_POST['nombre']);
$Apellido = utf8_decode($_POST['apellido']);
$Email = utf8_decode($_POST['email']);

$resultado=mysql_query("SELECT * FROM ".$db_table_name." WHERE Email = '".$Email."'", $db_connection);

if (mysql_num_rows($resultado)>0)
{

header('Location: Fail.html');

} else {

    $insert_value = 'INSERT INTO `' . $prueba. '`.`'.$datos.'` (`nombre` , `apellido` , `email`) VALUES 
    ("' . $Nombre . '", "' . $Apellido . '", "' . $Email . '")';

mysql_select_db($db_name, $db_connection);
$retry_value = mysql_query($insert_value, $db_connection);

if (!$retry_value) {
   die('Error: ' . mysql_error());
}

header('Location: Success.html');

}

mysql_close($db_connection);

我改变了这个$db_connection = mysql_connect("$localhost", "$root","");

到$db_connection = mysql_connect($db_host, $db_user,$db_password);，

这$resultado=mysql_query("SELECT * FROM ".$datos." WHERE Email = '".$Email."'", $db_connection);

到$resultado=mysql_query("SELECT * FROM ".$db_table_name." WHERE Email = '".$Email."'", $db_connection); 和这个

`mysql_select_db($prueba, $db_connection);`

要 mysql_select_db($db_name, $db_connection);

解析错误：语法错误，意外的“”“（T_CONSTANT_ENCAPSED_STRING），期望变量（T_VARIABLE）或'{'或'$'in
