如何解决XML Laravel 5.7中的foreach错误

Question

我想在Laravel 5.7中创建XML数据，然后使用Postman对其进行了测试。对于数据，我正在使用JSON。

这是我在JSON中的数据：

[
    {"fa_type_cd":"string","name":"Sting","user_value":"Sting","sort_seq":"1","type_cd":"string"},
    {"fa_type_cd":"string","name":"String","user_value":"String","sort_seq":"1","type_cd":"String"}
]

这是我在控制器中的功能，用于创建XML：

public function createXml(Request $request){
    $data = $request->input('data');
    $decode_data = json_decode($data);
    $xmlrequest = '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:c1c="http://splwg.com/C1CustomerContactMaintenance.xsd">
       <SOAP-ENV:Header xmlns:wsse="http://www.w3.org/2001/XMLSchema-instance">
        <wsse:Security>
            <wsse:UsernameToken>       
                <wsse:Username>Username</wsse:Username>
                <wsse:Password Type="PasswordText">Password</wsse:Password>        
            </wsse:UsernameToken>    
        </wsse:Security>  
       </SOAP-ENV:Header>
        <SOAP-ENV:Body>
            <C1FieldActivityMaintenance dateTimeTagFormat="CdxDateTime"  transactionType ="UPDATE" >

                        >

                            <FAStepsHeader
                                FieldActivityID="111" 
                                />

                                />
                            '
                                foreach ($decode_data as $key => $value) {
                                    '<FACharacteristicsRow

                                } 
                            '
                        </FACharacteristics>

                        </FaRem>
                        <FaLog>
                            <FaLogHeader
                                FieldActivityID="111" 
                                />
                            <FaLogRow
                                rowAction="Add" 
                                FieldActivityID="111" 
                                Sequence="2"
                                DateTime="2018-10-06 02:50:00" 
                                Details="" 
                                User="Users2" 
                                LogType="MSG" 
                                >
                            </FaLogRow>

            </C1FieldActivityMaintenance>
        </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>';
    print_r($xmlrequest);
}

我想在XML中解码后输入JSON数据，但是当我在Postman中运行它时，我会有这样的错误：

SymfonyComponentDebugExceptionFatalThrowableError: syntax error, unexpected 'foreach' (T_FOREACH)

如何解决此错误？

您不能仅在字符串中间使用 foreach()。如果您想正确执行此操作：

public function createXml(Request $request){
    $data = $request->input('data');
    $decode_data = json_decode($data);
    $xmlrequest = '
    <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:c1c="http://splwg.com/C1CustomerContactMaintenance.xsd">
       <SOAP-ENV:Header xmlns:wsse="http://www.w3.org/2001/XMLSchema-instance">
        <wsse:Security>
            <wsse:UsernameToken>       
                <wsse:Username>Username</wsse:Username>
                <wsse:Password Type="PasswordText">Password</wsse:Password>        
            </wsse:UsernameToken>    
        </wsse:Security>  
       </SOAP-ENV:Header>
        <SOAP-ENV:Body>
            <C1FieldActivityMaintenance dateTimeTagFormat="CdxDateTime"  transactionType ="UPDATE" >

                                />
    ';
    foreach ($decode_data as $key => $value) {
        $xmlrequest .='<FACharacteristicsRow

    ';
    print_r($xmlrequest);
}

Answer 2

简单答案

您不能在单引号之间使用foreach。您应该首先创建一个变量，然后在XML中引用它。

$foreachResult = "";
foreach ($decode_data as $key => $value) {
    $foreachResult += <--your xml code-->;
}

然后

<FACharacteristicsHeader
   FieldActivityID="111"/>' . $foreachResult . '/>

首选方法：

在PHP文件中确实很难看到并理解XML代码。您可以使用树枝在Laravel中渲染XML。
