如何重构这个以处理每个字母(a到z)我不想为每个字母重写查询。
显示HTML:
<div class="questionWrapper">
<div class="question">
<h3>A</h3>
<?php foreach ($categoryA as $category) : ?>
<p class="view"><?= $category['category']; ?></p>
<?php endforeach; ?>
</div>
</div>
查询示例:
$categoryA = query('SELECT * FROM category WHERE category LIKE "A%"',
array('category' => ['category']),
$conn);
$categoryB = query('SELECT * FROM category WHERE category LIKE "B%"',
array('category' => ['category']),
$conn);
功能:
function query($query, $bindings, $conn)
{
$stmt = $conn->prepare($query);
$stmt->execute($bindings);
return $stmt;
}
答案 0 :(得分:0)
我修复了你使用占位符:
$category = query('SELECT * FROM category WHERE category LIKE :category',
array(':category' => '%'.$letter.'%'),
$conn);
