Encoding Issue in get_all_user_info

[ahmedali5530]

Hi @cobisja,
i m using this library for fetching user information from machine but error occurs while triggering the get_all_user_info function, the error message is here

Warning: SimpleXMLElement::__construct(): Entity: line 1: parser error : Input is not proper UTF-8, indicate encoding ! Bytes: 0xFB 0x86 0x3C 0x2F in C:\Program Files (x86)\xampp\htdocs\hrm\libraries\tad\lib\TADResponse.php on line 462

Any ideas how to resolve this issue.

3 questions : 1) Your data have special characters like Chinese, Arabic or something like that?. 2) did you use the parameter "encoding" when you get a TAD-PHP instance?. 3) can you send me the sample code you used?

[ahmedali5530]

• I use simple Alphabetical characters while adding data into machine.
• I use this code while getting the instance of tad

$tad = (new TADFactory(['ip'=>'machine ip', 'com_key'=>0]))->get_instance();

• And use this for getting the user information from machine

$all_user_info = $tad->get_all_user_info()->to_array();

My friend, it seems the XML response received from your device is invalid in someway. To be sure please copy, paste and run, as an alone script, the following PHP code and send to me the response generated:

<?php
$your_ip = 'xxx.xxx.xx.xx'; // Set here your device's ip

$options = array(
    'location' => 'http://' . $your_ip . '/iWsService',
    'uri' => 'http://www.zksoftware/Service/message/'
);

$client = new SoapClient(null, $options);
$soapRequest = "<GetAllUserInfo><ArgComKey>0</ArgComKey></GetAllUserInfo>";

$response = $client->__doRequest($soapRequest, 'http://' . $your_ip . '/iWsService', '', '1.1');

echo '<pre>', var_dump($response), '</pre>'; // Please copy the whole string generated here and send it to me

I hope I can find out where the problem is. It is a little complicated to help you because I don't have a device where I can run some tests.

Here is the response which i get from machine according to your instructions

Well the response that you got from your device is obviously not well formed (according XML structure) and that's why you are getting the error:

Warning: SimpleXMLElement::__construct(): Entity: line 1: parser error : Input is not proper UTF-8, indicate encoding ! Bytes: 0xFB 0x86 0x3C 0x2F in C:\Program Files (x86)\xampp\htdocs\hrm\libraries\tad\lib\TADResponse.php on line 462

It's suppose your device should be return an XML response like the following:

<GetAllUserInfoResponse>
    <Row>
        <PIN>XXXXX</PIN>
        <Name>XXXX</Name>
        <Password>XXX</Password>
        <Group>X</Group>
        <Privilege>X</Privilege>
        <Card>XXXX</Card>
        <PIN2>XXXX</PIN2>
        <TZ1>XXX</TZ1>
        <TZ2>XXX</TZ2>
        <TZ3>XXX</TZ3>
    </Row>
    <Row>
       ...
    </Row>
</GetAllUserInfoResponse>

I have no idea why you are getting a not well-formed XML. Maybe is your device model (which I don't know what model you have, by the way). Maybe is the device's firmware version (TAD-PHP it's been tested on ZEM580, ZEM600 and few devices with ZEM800).

Sorry but at the moment I don't have any advice for you to solve this issue.

Hi @ahmedali5530 the problem is how are you sending data, if you look at line: "1421-weweweweee kkkiiikiik2 �123400678902180000", you can see a "diamond" with a question mark inside, that is the problem on sending XML data and convert it.

I think the solution is send the data without that signs or symbols.

I hope this help you.

[cobisja]

Maybe I'm wrong my friend but I agree with @JohanMa4. I think the problem is related with your data in your device.

It would be nice if you can tell me what device's model you have (including the firmware version).

[ahmedali5530]

Thanks @cobisja and @JohanMa4 for your suggestions, i deleted the users with different encoding and it worked.
By the way i m using Zkteco F18 machine.
