Question

在这段代码中，我有一个for循环，它通过数组中的所有结果然后看起来用户输入等于现在是$testsubject之后它检查凭证代码是否不是已过期，然后需要计算价格$testamount

的折扣

echo的

我有这个foreach循环，我希望它首先循环通过数组中的所有项目，然后如果`$ testsubject等于其中一个，请检查下一个事项，如果它们都不相等，那么显示最后一次回声。

所以基本上如果（$ testsubject == $ testVoucherArr ['code']）为true，请停止for each并检查下一个if语句，如果不是true则显示最后一次回显“这只需要显示什么时候没有结果“

的index.php

function display()
{
$arrContextOptions=array(
  "ssl"=>array(
    "verify_peer"=>false,
    "verify_peer_name"=>false,
  ),
); 

$getVoucherList = "https://www.planyo.com/rest/?method=list_vouchers&api_key=yourkey&resource_id=110556";
$cleanVoucherList = preg_replace("/ /", "%20", $getVoucherList);
$voucherlist = file_get_contents("$cleanVoucherList", false, stream_context_create($arrContextOptions));
$voucherList = json_decode($voucherlist, true);
$testsubject = "TESTVOUCHER-B";
$testamount = "5,00";
$doesvoucherexists = false;

foreach($voucherList['data']['results'] as $testVoucher => $testVoucherArr){
  if ($testsubject == $testVoucherArr['code']) {
       $doesvoucherexists = true;
        if (date("Y-m-d") <= $testVoucherArr['rental_end_date']) {
          echo "this code can be used <br>";
          echo $testamount - $testVoucherArr['discount_value'] . "<br>";
      }else{
        echo "this code is expired";
      };

         break;
   }
}
if ($doesvoucherexists === false) {
      echo "this needs to only show when there are no results <br>";
}

if(isset($_POST['submit']))
{
   display();
}}

如果我理解你想做什么，你必须移动

if ($doesvoucherexists === false) {

在foreach循环之外。

在else ;结束括号

之后，您还会遇到额外}的语法错误

告诉我以下代码是否适合您

function display()
{
    $arrContextOptions = array(
        "ssl" => array(
            "verify_peer" => false,
            "verify_peer_name" => false,
        ) ,
    );
    $getVoucherList = "https://www.planyo.com/rest/?method=list_vouchers&api_key=yourkey&resource_id=110556";
    $cleanVoucherList = preg_replace("/ /", "%20", $getVoucherList);
    $voucherlist = file_get_contents("$cleanVoucherList", false, stream_context_create($arrContextOptions));
    $voucherList = json_decode($voucherlist, true);
    $testsubject = "TESTVOUCHER-B";
    $testamount = "5,00";
    $doesvoucherexists = false;
    foreach($voucherList['data']['results'] as $testVoucher => $testVoucherArr) {
        if ($testsubject == $testVoucherArr['code']) {
            $doesvoucherexists = true;
            if (date("Y-m-d") <= $testVoucherArr['rental_end_date']) {
                echo "this code can be used <br />";
                echo $testamount - $testVoucherArr['discount_value'] . "<br />";
            }
            else {
                echo "this code is expired";
            }
            break;
        }

    }
    if ($doesvoucherexists === false) {
        echo "this needs to only show when there are no results <br />";
    }
}

if (isset($_POST['submit'])) {
    display();
}

完成整个foreach循环后做一些事情
