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:

Its docs in dutch so please convert it to english first by translate page :) — Anand Pandey, May 22 '18 at 06:54
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, May 25 '18 at 08:52
Their API must be broken, because you're doing it correctly according to their docs. http://cswdoc.imuisonline.com/wp-content/uploads/2015/05/cloudswitch.pdf — Chris C., May 31 '18 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, Jun 01 '18 at 06:07

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? — Anand Pandey, May 24 '18 at 09:44
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. — Zafahix, May 24 '18 at 09:51
{ "success": false, "error": "DOMDocument::loadXML(): StartTag: invalid element name in Entity, line: 2" } — Anand Pandey, May 24 '18 at 09:58
base64_encode is needed.Please see the doc.http://cswdoc.imuisonline.com/?page_id=382 — Anand Pandey, May 24 '18 at 10:36
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. — Zafahix, May 25 '18 at 10:32
$img_src = 'C:\Users\getpdf.pdf'; $file = file_get_contents($img_src); $byte_array = unpack("C*",$file); $data = serialize($byte_array); $str = base64_encode($data); — Anand Pandey, May 25 '18 at 10:36
The error now is "An internal error has occurred when creating the journal entry. Please contact MOUSE Software " — Anand Pandey, May 25 '18 at 10:37

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);

Its a jquery stuff and i want it on php. – Anand Pandey May 29 '18 at 12:25 — Anand Pandey, May 29 '18 at 12:25

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) :)
