How to convert Pdf file to byte array in php and send?

Question

I have found pdf to byte array and vice-versa in java,dotnet and python. But i want to convert pdf to byte array in php laravel. I am using "IMUIS" which is accounting software solution and need to sending journal entries from laravel lumen to "IMUIS" for processing.But it gives the error after converting.

"Foutmelding": "Kan een object van het type System.String niet converteren naar het type System.Byte[]."

In english that means

"Error message": "Can not convert a System.String object to the System.Byte [] type."

The documentation is given here:

doc link

Here is the code for it.

public function saveJournal($values = '') {
    //echo "adasd";dd();
    $partnerKey = $values->input('Partnerkey');
    $omgevingscode = $values->input('Environmentcode');  
    $file = file_get_contents($values->file('Pdffile'));
    $str = base64_encode($file);
    $options = array(
        \WsdlToPhp\PackageBase\AbstractSoapClientBase::WSDL_URL => env('IMUIS_URL'),
        \WsdlToPhp\PackageBase\AbstractSoapClientBase::WSDL_CLASSMAP => ClassMap::get(),
    );
    $login = new \mysdk\ImuisSDK\ServiceType\Login($options);
    if ($login->Login(new \mysdk\ImuisSDK\StructType\Login($partnerKey, $omgevingscode)) !== false) {
        $sessionid = $login->getResult()->SessionId;
    }

    $array = [
        'BOE' => [
           'JR' => '2018',
           'PN' => '5',
           'DAGB' => 20,
           'REK' => 20032,
           'TEGREK' => '40',
           'FACT' => 0,
           'BTW' => 4,
           'BEDRBOEK' => 123.45,
           'DAT' => '08-05-2018',
           'OPM' => 'Anand testing from wsdl',
           'BEDRBTW' => 21,
           'FACT' => 0,
           'OMSCHR' => 'Testing from wsdl api',
           'BOEKSTUK' => 2018075
        ],
        'DIGDOS' => [
            'FILE' => $str
        ]
    ];

    $journaalpost = ArrayToXml::convert($array, 'NewDataSet');//convert array to xml string

    $create = new \mysdk\ImuisSDK\ServiceType\Create($options);
    if ($create->CreateJournaalpost(new \mysdk\ImuisSDK\StructType\CreateJournaalpost($partnerKey, $omgevingscode, $sessionid, $journaalpost)) !== false) {
        $jsonResponse = $create->getResult();
    } else {
        $jsonResponse = $create->getLastError();
    }
    return $jsonResponse;
}

and here is the response as well:

Something is missing here. The error message you have shown is a C# error message, but your code is all PHP. What system is returning this error? — Rich
– Rich, Commented May 25, 2018 at 8:52
Their API must be broken, because you're doing it correctly according to their docs. cswdoc.imuisonline.com/wp-content/uploads/2015/05/… — Chris C.
– Chris C., Commented May 31, 2018 at 17:36
yes, i think it is something broken. But thousands of people using it. How can we solve this error? I didnt find any developer who use IMUIS already. — Anand Pandey

To convert PDF to byte array you will have to read the document using file_get_contents() and then parse it by function unpack().

<?php
    public function saveJournal($values = '') {
        $partnerKey = $values->input('Partnerkey');
        $omgevingscode = $values->input('Environmentcode');  
        $file = file_get_contents($values->file('Pdffile'));
        $byte_array = unpack("C*",$file);
        $base64_encode = base64_encode(serialize($byte_array));
        $options = array(
            \WsdlToPhp\PackageBase\AbstractSoapClientBase::WSDL_URL => env('IMUIS_URL'),
            \WsdlToPhp\PackageBase\AbstractSoapClientBase::WSDL_CLASSMAP => ClassMap::get(),
        );
        $login = new \mysdk\ImuisSDK\ServiceType\Login($options);
        if ($login->Login(new \mysdk\ImuisSDK\StructType\Login($partnerKey, $omgevingscode)) !== false) {
            $sessionid = $login->getResult()->SessionId;
        }

        $array = [
            'BOE' => [
               'JR' => '2018',
               'PN' => '5',
               'DAGB' => 20,
               'REK' => 20032,
               'TEGREK' => '40',
               'FACT' => 0,
               'BTW' => 4,
               'BEDRBOEK' => 123.45,
               'DAT' => '08-05-2018',
               'OPM' => 'Anand testing from wsdl',
               'BEDRBTW' => 21,
               'FACT' => 0,
               'OMSCHR' => 'Testing from wsdl api',
               'BOEKSTUK' => 2018075
            ],
            'DIGDOS' => [
                'FILE' => $base64_encode 
            ]
        ];

        $journaalpost = ArrayToXml::convert($array, 'NewDataSet');//convert array to xml string

        $create = new \mysdk\ImuisSDK\ServiceType\Create($options);
        if ($create->CreateJournaalpost(new \mysdk\ImuisSDK\StructType\CreateJournaalpost($partnerKey, $omgevingscode, $sessionid, $journaalpost)) !== false) {
            $jsonResponse = $create->getResult();
        } else {
            $jsonResponse = $create->getLastError();
        }
        return $jsonResponse;
    }
?>

so how to convert it to base64 encode() because we cant convert array from base64_encode() only convert string. Do you know that?

Zafahix Over a year ago

I updated the answer and added the corrected code. Try it. There is no need to use the function base64_encode() anymore. The function unpack() should work.

Anand Pandey Over a year ago

{ "success": false, "error": "DOMDocument::loadXML(): StartTag: invalid element name in Entity, line: 2" }

Anand Pandey Over a year ago

base64_encode is needed.Please see the doc.cswdoc.imuisonline.com/?page_id=382

Zafahix Over a year ago

I updated the code in answer. Try get file by file_get_contents(), next use unpack() for covert to byte array and base64_encode(serialize($byte_array)) to get encoded array.

I think the problem is that WsdlToPhp has constructed client code which is sending the PDF entity as a String, when it needs to be a byte[].

So I think the problem may be in code that is not shown here.

Can you take a look at the code generated by WsdlToPhp and see if you have any flexibility in how the $journaalpost is serialized to see if you can fix in there?

// Convert the Base64 string back to text.
var byteString = atob(data.reportBase64Bytes);

// Convert that text into a byte array.
var ab = new ArrayBuffer(byteString.length);
var ia = new Uint8Array(ab);
for (var i = 0; i < byteString.length; i++) {
    ia[i] = byteString.charCodeAt(i);
}

// Blob for saving.
var blob = new Blob([ia], { type: "application/pdf" });

// Tell the browser to save as report.pdf.
saveAs(blob, "report.pdf");

// Alternatively, you could redirect to the blob to open it in the browser.
//document.location.href = window.URL.createObjectURL(blob);

There is a "bug" in the IMUIS software so it cant be possible to link a pdf file from php. Its may be done by Dotnet because its native language and the entire system built by it. Thanks to all of my SO friends for your efforts to helps me to find the issue, i have confirmed this information after call support. So in the future no one get stuck (afterall maybe end of 2018) :)
