// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}



$row['from'] = 1000;
$row['to'] = 1999;

$start = $row['from'];
$to = $row['to'];
$step = 50;
$values = array();

$query = "INSERT INTO tab2 VALUES (from, to) ";

for($i = $start; $i <= $to; $i += $step) {
    $values[] = '('.$i.', '.($i + ($step - 1)).')';
}

$query .= implode(', ', $values).';';

使用 MariaDB，您可以使用从起始值到结束值的 for 循环来创建查询以将值插入到您想要的 table。

$servername = "localhost";
$username = "root";
$password = "pass";
$dbname = "number";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_errno) {
    echo 'Error: '.$conn->connect_error;
    exit();
}

$row['from'] = 1000;
$row['to'] = 1999;

$start = $row['from'];
$to = $row['to'];
$step = 50;
$values = array();

$query = "INSERT INTO tab2 VALUES ";

for($i = $start; $i <= $to; $i += $step) {
    $values[] = '(DEFAULT, '.$i.', '.($i + ($step - 1)).')';
}

$query .= implode(', ', $values).';';
if (!$conn->query($query)) {
    echo $conn->error;
}
