You are searching for <b style="font-family:Zawgyi-One"><?php echo $spre; ?> - <?php echo $sone; ?><?php echo $stwo; ?><?php echo $sthree; ?><?php echo $sfour; ?><?php echo $sfive; ?><?php echo $ssix; ?></b><br /><br />

但是当我搜索时，结果显示在
中您正在搜索c1 - 000000
但我喜欢将“c1”显示为က（က是unicode）。我将CSV文件导入我的数据库而不包括unicode。
答案 0 :(得分：3)
value=""的内容是浏览器发送给PHP的内容，如果您想要查看该选项中的确切内容，则将其编码为
<select name="name">
<option value="Joe">Joe</option>
<option value="Micheal">Micheal</option>
<option value="Sean">Sean</option>
</select>
然而，在id中对value="<?php echo $id;?>"之类的内容进行编码是正常的，因为您可以更轻松地检索与该名称相关联的数据。
啊我刚刚注意到你说你正在使用多项选择或至少也想要。
在这种情况下，您需要更改<select>标签，如此
<select name="name" multiple="multiple">
<option value="Joe">Joe</option>
<option value="Micheal">Micheal</option>
<option value="Sean">Sean</option>
</select>
然后在您的PHP代码中，$_POST['name']变量将作为数组返回，因此您将按以下方式处理： -
if ( isset( $_POST['name'] ) ) {
foreach ( $_POST['name'] as $selected_name ) {
echo $selected_name;
}
}
