MySQL查询返回不可能的值

Question

不确定我是否疯了，这就是我的数据库的样子：

+--------+-----+-----+-----+-------+-------+--------+------+-------+-----------+
| itemid | sku | upc | ean | title | style | gender | size | color | modelcode |
+--------+-----+-----+-----+-------+-------+--------+------+-------+-----------+
|   21   |00021| xxx | xxx | Bolt  | Tank  | Girls  | Small| Blue  | 60        |
+--------+-----+-----+-----+-------+-------+--------+------+-------+-----------+

这是我运行的查询：

$query = "SELECT itemid,
upc,
sku,
ean,
title,
style,
gender,
color,
modelcode,
price,
quantity,
pagelink,
imagelinksmall,
description

from clothing where modelcode = $modelcode";

并且正在运行var_dump($rows[0]['size']);我得到的值"XX-Small"应该只是"Small"。

每个modelcode有多个大小，并且其间有很多if / else语句。这是整个脚本：

$query = "SELECT itemid,
upc,
sku,
ean,
title,
style,
size,
gender,
color,
modelcode,
price,
quantity,
pagelink,
imagelinksmall,
description

from clothing where modelcode = $modelcode"; 

// This function is static for 5 different sizes, from X-Small to X-Large. If there is an XX-Small available, the script will only go to Large. If there's an XX-Large, the script will stop where
// it normally does, which is at X-Large.

function resultToArrays($result) {            // This Function declares an array as $rows, loops through each row while there's any left, and stores it into the array
  $rows = array();                            // Declares $rows as an array
  while ($row = $result -> fetch_assoc()) {   // The while loop that iterates through any and all pulled rows
    $rows[] = $row;                           // Stores the information
  }
  return $rows;
};

$result = $con->query($query);
$rows = resultToArrays($result);

$color = $rows[0]['color'];
$style = $rows[0]['style'];
$description = $rows[0]['description'];
$imagelinksmall = $rows[0]['imagelinksmall'];
$gender = $rows[0]['gender'];

我已经对所有内容进行了三次检查，而且我现在真的很茫然。
