javascript - 使用 php 数组生成选择选项

Question

我有一个“州”类别选择，它根据所选州显示 4 个“运营商”选择之一。我希望 php 使用各自的选项填充“运营商”选择。我搜索了堆栈，我确信那里有几个答案，但由于我的 php 新手身份，我很难理解其中的逻辑。也就是说，我目前拥有的 php 是我被指示使用/回收的，并不反射(reflect)我的 php 技能。我真的需要这个家伙的帮助!

我的 html 开头有一些额外的 PHP:

    $state = new state;
$state_arry = $state->state_options("NY");

//For Connecticut
$sqlCT = mysql_query("SELECT * FROM `gia_survey_allyears_company` WHERE `State`='CT' and `show`='Y' order by Name");
//For New York
$sql = mysql_query("SELECT * FROM `gia_survey_allyears_company` WHERE `State`='NY' and `show`='Y' order by Name");
//For New Jersey
$sqlNJ = mysql_query("SELECT * FROM `gia_survey_allyears_company` WHERE `State`='NJ' and `show`='Y' order by Name");
//For New Hampshire
$sqlNH = mysql_query("SELECT * FROM `gia_survey_allyears_company` WHERE `State`='NH' and `show`='Y' order by Name");

$row = mysql_fetch_assoc($sql);

//For New York
do {
    $company_arry[]=array('Name'=>$row['Name'],'Id'=>$row['ID']);
} while ($row = mysql_fetch_assoc($sql));

//For New Jersey
do {
    $company_arryNJ[]=array('Name'=>$row['Name'],'Id'=>$row['ID']);
} while ($row = mysql_fetch_assoc($sqlNJ));

//For New Jersey
do {
    $company_arryNH[]=array('Name'=>$row['Name'],'Id'=>$row['ID']);
} while ($row = mysql_fetch_assoc($sqlNH));

//For Connecticut
do {
    $company_arryCT[]=array('Name'=>$row['Name'],'Id'=>$row['ID']);
} while ($row = mysql_fetch_assoc($sqlCT));

$total = count($company_arry);
$col1 = round($total/2);
$col2 = $total-1

;

此 PHP 生成我在纽约运营商选择中需要的列表(作为示例):

 <? 
            for ($i1=0; $i1<= $col1; $i1++) { 
                echo "<a href=\"company.php?id=".$company_arry[$i1]['Id']."\">".$company_arry[$i1]['Name']."</a><br>";
            } 
            ?>

Answer 1

也许这会解决它

$options = '';
foreach($company_arry as $company) {
    $options .= "<option value='" . $company['Id'] . "'>" . $company['Name'] . "</option>";
}
echo $options;
