添加一個變量MySQL查詢

Question

我有內部的變量$text = "sometexthere"

我想補充這一變量$text以下MySQL查詢內，而不是sometexthere

$query = "SELECT sum(nbr) AS sum FROM table2 WHERE name LIKE '%sometexthere%'";

我試圖做的是在許多方式如

$query = "SELECT sum(stats) AS sum FROM download WHERE filename LIKE '%' . $text . '%'";

和

$name = "'%' . $text . '%'"; 
$query = 'SELECT sum(stats) AS sum FROM download WHERE filename LIKE '.$name.''; 

但不工作：/

Answer 1

嘗試用

$query = "SELECT sum(stats) AS sum FROM download WHERE filename LIKE '%$text%'"; 

，避免這條線

$name = "'%' . $text . '%'"; 

或嘗試這樣，

$name = "%".$text."%"; 
$query = "SELECT sum(stats) AS sum FROM download WHERE filename LIKE '$name'"; 

Answer 2

嘗試

$query = "SELECT sum(stats) AS sum FROM download WHERE filename LIKE '%" . $text . "%'";
