Question

所以我有这个foreach循环检查$testsubject是否等于数组的结果。

但我希望它首先检查所有结果，如果一个是真的，那么进一步检查日期，否则只是回应凭证不是核心。

代码的目的是用户输入的凭证代码现在为$testsubject，而不是我检查系统中是否存在凭证如果是，我检查它是否与日期一起过期功能，然后我削减了价格$testamount的折扣。

的index.php

function display()
{
    $arrContextOptions = [
        "ssl" => [
            "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";
    $testamount       = "5,00";
    foreach ($voucherList['data']['results'] as $testVoucher => $testVoucherArr) {
        if ($testsubject == $testVoucherArr['code']) {
            echo $testsubject . " is not equal to " . $testVoucherArr['code'] . "<br>";
            echo $testVoucherArr['rental_end_date'] . "<br>";
            echo $testVoucherArr['discount_value'] . "<br>";
            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 cannot be used";
            }
            ;
        } else {
            echo $testsubject . " is not equal to " .
                $testVoucherArr['code'] . "<br>";
        }
    }
}

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

Answer 1

首先将标志设置为true，然后如果出现错误，则将标志循环设置为false。然后测试旗帜：

$flag = true;                          // SET A FLAG
foreach($a as $b){
    if($b !== 'Hello')$flag = false;   // IF contidtion not met, set flag to true
    }
if($flag === false){                   // TEST IF flag result
    echo 'Dear oh dear';die;
    }
foreach(....){                         // GO ON if flag === true
    ....
    }

这对你有用吗？如果代码有效，则输入检查日期的函数。函数结束后，foreach循环将以“break;”

结束

function testVoucherDate($voucher)
{
    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 cannot be used";
    };
}

foreach ($voucherList['data']['results'] as $testVoucher => $testVoucherArr) {
    if ($testsubject == $testVoucherArr['code']) {
        echo $testsubject . " is not equal to " . $testVoucherArr['code'] . "<br>";
        echo $testVoucherArr['rental_end_date'] . "<br>";
        echo $testVoucherArr['discount_value'] . "<br>";
        testVoucherDate($testVoucherArr);
        break;
    } else {
        echo $testsubject . " is not equal to " .
            $testVoucherArr['code'] . "<br>";
    }
}

编辑：我把这个函数放在循环上面，所以不会出现未定义函数的错误

首先循环通过一切，而不是1是真的做某事
