我正试图在foreach中回显数组的结果以进行定位，但遇到了数组问题。
<select name="locale">
<?php
foreach ($locales at $location => $lo) {
echo '<option value="' . $lo[0] . '">' . $lo[1] . '</option>';
}
?>
</select>
数组如下所示；

我正在尝试将位置代码输入到值中，并在显示的选项中获取易于读取的位置。只是运气不太好。
非常感谢：-(
$lo不是一个数组，它是一个类似于'Afar (Djibouti)'的字符串。$lo[0]是第一个字符，$lo[1]是第二个字符。
您希望在选项中使用$location和$lo。当您写入foreach ($locales as $location => $lo)时，数组键进入$location，相应的值进入$lo。
还有一个拼写错误：at应该是as。
foreach ($locales as $location => $lo) {
echo '<option value="' . $location . '">' . $lo . '</option>';
}
$lo[0]不包含区域设置。它被存储在$lo中，并且根据foreach循环的定义，该位置已经在$location中。
<select name="locale">
<?php
foreach ($locales at $lo => $location) {
echo '<option value="' . $lo . '">' . $location . '</option>';
}
?>
</select>
