PHP 解析错误：语法错误，PHP 8.1 错误消息中的意外标记“public”

问题描述 投票：0回答：2

在 PHP 8.1 中运行时会触发上述错误消息。

无法发现任何明显的问题，关于需要更改以下代码的位置以消除此错误消息。

 public function process_button()
{
    $sid = zen_session_name() . '=' . zen_session_id();
    $formEntries = $this->buildStandardTransactionDetails();
    $formEntries['SuccessURL'] = str_replace('&', '&', zen_href_link(FILENAME_CHECKOUT_PROCESS, $sid, 'SSL', false));
    $formEntries['FailureURL'] = str_replace('&', '&', zen_href_link(FILENAME_CHECKOUT_PROCESS, $sid, 'SSL', false));
    $processButtonString = SagepayUtil::processCryptEntries($formEntries);

    $crypt = SagepayUtil::encryptAndEncode($processButtonString, MODULE_PAYMENT_SAGEPAY_ZC_FORM_PASSWORD);

    $transaction_type = strtoupper(MODULE_PAYMENT_SAGEPAY_ZC_FORM_TXTYPE);
    $this->errorLog(array(
        array('title' => 'Transaction Type', 'content' => $transaction_type),
        array('title' => 'Submit Data', 'content' => $processButtonString)
    ));

    $process_button_string = zen_draw_hidden_field('VPSProtocol', self::SP_PROTOCOL_VERSION) .
        zen_draw_hidden_field('TxType', $transaction_type) .
        zen_draw_hidden_field('Vendor', MODULE_PAYMENT_SAGEPAY_ZC_FORM_VENDOR_NAME) .
        zen_draw_hidden_field('ReferrerID', 'BB5F9F0D-8982-4203-AFD4-AF78017E4B92') .
        zen_draw_hidden_field('Crypt', $crypt);
    return $process_button_string;
}

错误指向第一行代码（如下）：

 public function process_button()

这个函数不是类的一部分。所以删除

public
关键字只是

function process_button()

如果您尝试将 

public
关键字添加到 PHP 中的函数并且它给您一个错误，这可能是因为您没有在类中使用它。

所以，在这里你也在做同样的事情，你将 public 关键字添加到一个不在任何类中的函数。

所以，解决这个问题的方法是简单地从函数前面删除

public
关键字，或者在某个类中定义函数，如下所示：

<?php

class Test{
    public function process_button()
    {
        $sid = zen_session_name() . '=' . zen_session_id();
        $formEntries = $this->buildStandardTransactionDetails();
        $formEntries['SuccessURL'] = str_replace('&amp;', '&', zen_href_link(FILENAME_CHECKOUT_PROCESS, $sid, 'SSL', false));
        $formEntries['FailureURL'] = str_replace('&amp;', '&', zen_href_link(FILENAME_CHECKOUT_PROCESS, $sid, 'SSL', false));
        $processButtonString = SagepayUtil::processCryptEntries($formEntries);

        $crypt = SagepayUtil::encryptAndEncode($processButtonString, MODULE_PAYMENT_SAGEPAY_ZC_FORM_PASSWORD);

        $transaction_type = strtoupper(MODULE_PAYMENT_SAGEPAY_ZC_FORM_TXTYPE);
        $this->errorLog(
            array(
                array('title' => 'Transaction Type', 'content' => $transaction_type),
                array('title' => 'Submit Data', 'content' => $processButtonString)
            )
        );

        $process_button_string = zen_draw_hidden_field('VPSProtocol', self::SP_PROTOCOL_VERSION) .
            zen_draw_hidden_field('TxType', $transaction_type) .
            zen_draw_hidden_field('Vendor', MODULE_PAYMENT_SAGEPAY_ZC_FORM_VENDOR_NAME) .
            zen_draw_hidden_field('ReferrerID', 'BB5F9F0D-8982-4203-AFD4-AF78017E4B92') .
            zen_draw_hidden_field('Crypt', $crypt);
        return $process_button_string;
    }
}
?>

如果不想在类中定义函数，请尝试以下代码：

<?php

     function process_button()
    {
        $sid = zen_session_name() . '=' . zen_session_id();
        $formEntries = $this->buildStandardTransactionDetails();
        $formEntries['SuccessURL'] = str_replace('&amp;', '&', zen_href_link(FILENAME_CHECKOUT_PROCESS, $sid, 'SSL', false));
        $formEntries['FailureURL'] = str_replace('&amp;', '&', zen_href_link(FILENAME_CHECKOUT_PROCESS, $sid, 'SSL', false));
        $processButtonString = SagepayUtil::processCryptEntries($formEntries);

        $crypt = SagepayUtil::encryptAndEncode($processButtonString, MODULE_PAYMENT_SAGEPAY_ZC_FORM_PASSWORD);

        $transaction_type = strtoupper(MODULE_PAYMENT_SAGEPAY_ZC_FORM_TXTYPE);
        $this->errorLog(
            array(
                array('title' => 'Transaction Type', 'content' => $transaction_type),
                array('title' => 'Submit Data', 'content' => $processButtonString)
            )
        );

        $process_button_string = zen_draw_hidden_field('VPSProtocol', self::SP_PROTOCOL_VERSION) .
            zen_draw_hidden_field('TxType', $transaction_type) .
            zen_draw_hidden_field('Vendor', MODULE_PAYMENT_SAGEPAY_ZC_FORM_VENDOR_NAME) .
            zen_draw_hidden_field('ReferrerID', 'BB5F9F0D-8982-4203-AFD4-AF78017E4B92') .
            zen_draw_hidden_field('Crypt', $crypt);
        return $process_button_string;
    }

?>

在这里，在上面的代码中，我只是删除了访问说明符

public
