从数据库mysql中的函数php插入值

Question

im testing insert al ip's from an array created with one function in php, in one database..

I have this code:

<?php

//Funcion IP
$range='192.168.3.0/24';

function rango($range){
    $parts = explode('/',$range);
    $exponent = 32-$parts[1].'-';
    $count = pow(2,$exponent);
    $start = ip2long($parts[0]);
    $end = $start+$count;
    return array_map('long2ip', range($start+1, $end-2) );
}



//Conexion a la Base de datos
$mysqli = new mysqli("localhost", "root", "", "ips");
if ($mysqli->connect_errno) {
    echo "Falló la conexión con MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}

//Elimina la tabla si existe
if (!$mysqli->query("DROP TABLE IF EXISTS prueba3") ||
    //Crea la tabla
    !$mysqli->query("CREATE TABLE prueba3(ip VARCHAR(30), estado VARCHAR(30))") ||
    //Inserta valores en la tabla

    foreach((rango($range)) as $i)
    {
        !$mysqli->query("INSERT INTO prueba3 (ip, estado) VALUES (". $i .", 'Libre')");
    }

    /*!$mysqli->query("INSERT INTO prueba3(ip, estado) VALUES ('192.168.3.1', 'Libre')")) { */
    //Si falla la creacion de la tabla
    echo "Falló la creación de la tabla: (" . $mysqli->errno . ") " . $mysqli->error;
}
?>

I need insert each value from that array, and i dont know how.. The problem is the 'foreach' inside the 'if' to insert them..

How can i solve this?

I still don't know why you're dropping the table each time but you can try this code, it does what you need BTW you were missing quotes around the value, it is a string so it does need to be enclosed within quotes

<?php

//Funcion IP
$range='192.168.3.0/24';

function rango($range){
    $parts = explode('/',$range);
    $exponent = 32-$parts[1].'-';
    $count = pow(2,$exponent);
    $start = ip2long($parts[0]);
    $end = $start+$count;
    return array_map('long2ip', range($start+1, $end-2) );
}



//Conexion a la Base de datos
$mysqli = new mysqli("localhost", "root", "MYSQL123", "ips");
if ($mysqli->connect_errno) {
    echo "Falló la conexión con MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}

//Elimina la tabla si existe
if ($mysqli->query("DROP TABLE IF EXISTS prueba3") AND $mysqli->query("CREATE TABLE prueba3(ip VARCHAR(30), estado VARCHAR(30))")){
    //Inserta valores en la tabla

    foreach((rango($range)) as $i)
    {
      $query = $mysqli->query("INSERT INTO prueba3 (ip, estado) VALUES ('". $i ."', 'Libre')");
        if($query){
          echo "Inserted " . $i . "<br/>";
        }else{
          echo "error ...(" . $mysqli->errno . ") " . $mysqli->error . "<br />";
        }
    }

    /*!$mysqli->query("INSERT INTO prueba3(ip, estado) VALUES ('192.168.3.1', 'Libre')")) { */
    //Si falla la creacion de la tabla

}else{
  echo "Falló la creación de la tabla: (" . $mysqli->errno . ") " . $mysqli->error;
}
?>
