PHP数组未在HTML中显示选择列表

我有一个带有状态列表的数组，我正试图让它显示在我的选择列表中。我没有收到任何错误，但选择列表中没有显示任何选项。我只是想让它在数组中循环并在HTML中显示状态

function statesList() {
$states = array('AL'=>"Alabama",
                'AK'=>"Alaska",
                'AZ'=>"Arizona",
                'AR'=>"Arkansas",
                'CA'=>"California",
                'WY'=>"Wyoming");
return $states;
}

$email_form = '<?php $states = statesList(); ?>
<form class="aw-contact-form" method="post" action="' . get_permalink() . '">
        <label for="cf_state">' . $label_state . '</label>
            <select name="state" id="cf_state">
                <option selected="selected"></option>
                <?php foreach($states as $key=>$value) { ?>
                <option value="<?php echo $key; ?>"><?php $value; ?></option>
                <?php } ?>
            </select>
</form>';

return $email_form;

函数状态列表（）{
$states=数组（'AL'=>“阿拉巴马”，
“AK”=>“阿拉斯加”，
“AZ”=>“亚利桑那州”，
“AR”=>“阿肯色州”，
“加州”=>“加州”，
“怀俄明州”=>“怀俄明州”）；
返回$states；
}
$email\u form='1
' . $给州贴上标签。”
是的，语法有问题，foreach被放在字符串中，因此它被解析为字符串，而不是要执行的php代码。$states也是空的，因为它被放置在函数之外。要获得$states值，必须调用函数。
这是固定版本：

function statesList() {
$states = array('AL'=>"Alabama",
                'AK'=>"Alaska",
                'AZ'=>"Arizona",
                'AR'=>"Arkansas",
                'CA'=>"California",
                'WY'=>"Wyoming");
return $states;
}    


$email_form = '<form class="aw-contact-form" method="post" action="' . get_permalink() . '">
        <label for="cf_state">' . $label_state . '</label>
            <select name="state" id="cf_state">
                <option selected="selected"></option>';

$states = statesList();
foreach ($states as $key => $value) {
    $email_form .= '<option value="' . $key . '">' . $value . '</option>';
}
$email_form .= '</select>
</form>';

return $email_form;

函数状态列表（）{
$states=数组（'AL'=>“阿拉巴马”，
“AK”=>“阿拉斯加”，
“AZ”=>“亚利桑那州”，
“AR”=>“阿肯色州”，
“加州”=>“加州”，
“怀俄明州”=>“怀俄明州”）；
返回$states；
}    
$email\u form='1
' . $给州贴上标签。”
';
$states=statesList（）；
foreach（$key=>$value）{
$email_form.=''.$value'；
}
$email_form.='
';
返回$email_表格；

试试这个：

<?php 
error_reporting(0);
function statesList() {
$states = array('AL'=>"Alabama",
                'AK'=>"Alaska",
                'AZ'=>"Arizona",
                'AR'=>"Arkansas",
                'CA'=>"California",
                'WY'=>"Wyoming");
return $states;
}
$states = statesList(); 
$email_form .= '<form class="aw-contact-form" method="post" action="' . get_permalink() . '">
                <label for="cf_state">' . $label_state . '</label>
                <select name="state" id="cf_state">
                <option selected="selected"></option>';
                foreach($states as $key=>$value) { 
                $email_form .= '<option value="'.$key.'">'.$value.'</option>';
                 } 
            $email_form .= '</select>
            </form>';

return $email_form;

?>
