在MYSQL SELECT中連接PHP變量

Question

我想連接MYSQL SELECT QUERY中的PHP變量。但迄今爲止沒有任何工作。

$nkFetch = function($tableNo) use ($link){ 

    $tableQuery = 'SELECT * FROM table.$tableNo'; <------------this 

    $res = mysqli_query($link, $tableQuery); 

    if (!mysqli_query($link, $tableQuery)) { 
     printf("Errormessage: %s\n", mysqli_error($link)); 
    } 

    $table = array(); 

    while ($row = mysqli_fetch_array($res)){ 
     $table[] = $row; 
    } 

    shuffle($table); 

    foreach($table as $row){ 
     echo "<li>" . $row['WORD'] . "</li>"; 
    } 

} 

Answer 1

$tableQuery = "SELECT * FROM table.$tableNo"; 

或

$tableQuery = 'SELECT * FROM table.' . $tableNo; 

或

$tableQuery = "SELECT * FROM table.{$tableNo}"; 

或

$tableQuery = sprintf("SELECT * FROM table.%s", $tableNo);
