Base64_decode to PDF - php

I am working with an XML file that provides a base64 encoded PDF document. When I take the encoded string and enter it into the base64 to PDF converter located here it works fine and decodes to a valid PDF. However when I use PHP base64_decode($validStr) I get garbage back to the screen. Here is my code.
<?php
header("Content-type: application/pdf");
$imageParam=array(
'pCompanyID'=>1,
'pSysUser'=>'dburchfield',
'pDocID'=>588690
);
$wsdl="http://192.168.0.31/WSSmartConnect/cCustomerDocument.asmx?wsdl";
$client = new SoapClient($wsdl, array('trace' => 1));
$soapCall = $client->GetDocumentImage($imageParam);
$response = ($client->__getLastResponse());
$str = implode('', preg_split('/\s*/', $response));
$bin = base64_decode($str);
echo $bin;
?>
Here is the result when it renders on the web site:

Quoted-printable Email Subject lines not getting decoded by email clients

I've written a WordPress plugin which sends out new post notifications. There is a setting to convert subject lines from html entites to quoted-printable so they'll display in UTF-8 on any email client. A few weeks ago I started getting reports that the quoted-printable subject line was being kept as-is instead of being decoded.
Sample Subject header:
Subject: =?UTF-8?Q?[Pranamanasyoga]=20Foro=20Pranamanasyoga=20:=20estr?= =?UTF-8?Q?=C3=A9s=20y=20resilencia?=
I cannot replicate it locally and have not been able to find any common denominators between reporters.
The code that generates the quoted-printable line is this:
<?php
$enc = iconv_get_encoding( 'internal_encoding' ); // this is UTF-8
$preferences = ['input-charset' => $enc, 'output-charset' => "UTF-8", 'scheme' => 'Q' ];
$filtered_subject = '[Pranamanasyoga] Foro Pranamanasyoga : estrés y resilencia';
$encoded = iconv_mime_encode( 'Subject', html_entity_decode( $filtered_subject ), $preferences );
$encoded = substr( $encoded, strlen( 'Subject: ' ) );
If I try decoding it, it works fine:
$decoded = iconv_mime_decode($encoded, 0, "UTF-8");
var_dump(['encoded' => $encoded, 'decoded' => $decoded])."\n";
Result:
array(2) {
["encoded"]=>
string(102) "=?UTF-8?Q?[Pranamanasyoga]=20Foro=20Pranamanasyoga=20:=20estr?=
=?UTF-8?Q?=C3=A9s=20y=20resilencia?="
["decoded"]=>
string(59) "[Pranamanasyoga] Foro Pranamanasyoga : estrés y resilencia"
}
One thing I noticed, but think is not related is that my code actually adds a newline before the second =?UTF-8?Q? piece and the email subject header does not have it. Decoding the strings with- and without the newline works the same.
Does anyone have ideas/suggestions on what may be causing the email clients (Gmail included) to display the string as-is, instead of decoding it to UTF-8?
P.S. While writing this I saw a suggestion to use mb_encode_mimeheader() in a different thread. It seems to work well with iconv_mime_decode() in my test code, but the output string is indeed different from the original one:
[Pranamanasyoga] Foro Pranamanasyoga : =?UTF-8?Q?estr=C3=A9s=20y=20resile?=
=?UTF-8?Q?ncia?=
Could it be that email clients would prefer this format over the original one?

PHPExcel Csv reader set encoding

I have this so far, but when I read from my csv I get an empty value because it is a non utf-8 encoded csv file.
public function process_woe()
{
$objPHPExcel = new PHPExcel();
$woe_processed = $objPHPExcel->setActiveSheetIndex( 0 );
$objReader = PHPExcel_IOFactory::load( $this->woe_filepath );
$woe = $objReader->getActiveSheet();
$rcount = 1;
$rncount = 1;
}
This string returns an empty string when I try to write it on a utf-8 encoding:
"Caruso�s Prostate EZE MAX health indications:
� Management of symptoms Medically Diagnosed Prostate Enlargement
� Prostate gland health
� Antioxidant for the prostate gland"
When I try to use setInputEncoding() I get an error, for example:
$objReader->setInputEncoding('ISO');
$woe->setInputEncoding('ISO-8859-7');
$woe->setInputEncoding('ISO-8859-1');
Fatal error: Uncaught Error: Call to undefined method PHPExcel_Worksheet::setInputEncoding() –

Convert Binary to File Using PHP

I'm using a service that gives you a wav file. this service gives me base64 binary code as a result. I want to convert it to a wav file.
I've been googling for it and couldn't find anything. here is my code :
$wsdl=' < url > ';//url to WSDL
$client = new SoapClient($wsdl);
$param=array(
'userName'=>' < my username> ',
'password'=>' < my password > ',
'messageId'=>1063716
); // parameters needed to download the file
try{
$res=$client->DownloadMessage($param) ;
$base64Binary = $res->DownloadMessageResult;
echo $base64Binary;
}catch(Exception $e){
echo '<pre>' ;
var_dump($e->getMessage());
echo '</pre>' ;

is this a base 64 binary? if it is, how to convert it to a wav file?
The string you're echoing looks like a plain wav stream. Just write it to a file without any decoding and you'll end up with a wav file. Be sure to use binary mode when writing the file.
$ptr = fopen("file.wav", 'wb');
fwrite($ptr, $e->getMessage());
fclose($ptr);
Wav header info: https://en.wikipedia.org/wiki/WAV#RIFF_WAVE
If the base64 encoded data already represents an MP3 file, it should be as easy as decoding the base64 data and storing it in a file:
file_put_contents('audio.mp3', base64_decode($base64Binary));

PHP/Python json_decode doesn´t display special characters like €

I got a json which is generated in a python program and looks like this:
{"0": {"ausschreiber": "Beispiel; Zeitarbeit GmbH", "beschreibung": "\r\nF\u00fcr unseren Kunden suchen wir motivierte studentische Aushilfen auf flexibler Stundenbasis (450\u0080-Basis)", "datum": "17.11.2016", "name": "Studentische Hilfskr\u00e4fte gesucht", "email": "info#hindi.de"}}
now i am decoding the json in my php program to get an associative array and display this on the website.
The Problem is that the special characters like the € char are not displayed but special chars like ö ä ü are displayed.
Here is the php program:
<?php
header('Content-Type: text/html; charset=utf-8');
function compare($old_data, $new_data){
$old_result = json_decode($old_data, true);
$new_result = json_decode($new_data, true);
echo $new_result[0]['beschreibung'];
}
function go4it(){
$db_data=json_content(); //creates the json from the Database
$crawler_data = file_get_contents('http://localhost/phppath/python_program.cgi'); //calls the cgi which returns the json
compare($db_data, $crawler_data);
}
go4it();
What i tried:
set the header to utf-8
$new_result = json_decode(utf8_encode($new data), true);
iconv_set_encoding("internal_encoding", "UTF-8");
iconv_set_encoding("input_encoding", "UTF-8");
iconv_set_encoding("output_encoding", "UTF-8");
Thanks for your help!
EDIT 1
so it seems like the issue is located in the python program, thanks to #FranzGleichmann . I think the problem is with the encoding of the page where i get the content from. The page says it is ISO-8859-1 so i tried this:
url = 'https://www.example.com'
source_code = requests.get(url)
plain_text = source_code.text
plain_text.decode('iso-8859-1', 'ignore').encode('utf8', 'ignore')
print(plain_text.encoding)
but then i get the error: "UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 8496: ordinal not in range(128)"
it was a problem with the python script

How do I prevent that the "<<" breaks the String

I tryed to build a FDF-File in php but i have problems with "<<". It's a bit strange the "<<" everything was before the string is deleted. I know the character is an operator but how can I use it to construct a string now?
here is my code:
$fdf = '%FDF-1.2
1 0 obj<</FDF<< /Fields[';
$fields = "";
foreach($dataContainer as $data)
{
if(array_key_exists($data['fieldname'], $this->fieldSet))
{
$field = '('.$data['fieldname'].')';
$value = '('.$data['content'].')';
$fields.='<</T'.$field.'/V'.$value.'>>';
echo $fields." ".$data['fieldname']."<br />";
}
}
$fdf.= $fields;
$fdf.= '] >> >>
endobj
trailer
<</Root 1 0 R>>
%%EOF';
and the output is:
<
<>
<><>
<><><>
<><><><>
Has anyone a solution for this?
Your PDF is fine, there is nothing wrong with << or anything else in the code. The only problem is that you probably dump the generated PDF content directly and, because nobody tells it otherwise, the browser tries to interpret it as HTML.
The solution is very simple: use function header() before outputting the PDF to tell the browser the correct type of the content you send:
header('Content-Type: application/pdf');
// ... Generate the PDF here
// ... and output it
echo($fdf);
That's all. Now, the browser knows the body of the response is not HTML and it won't try to display it, except if it knows how to read PDF (which the latest versions of Firefox and Chrome apparently do).
Depending on the browser and its settings, it will either display the PDF content rendered (as it would appear on the paper on printing) or it will open the default PDF viewer installed on the computer (Adobe Acrobat Reader, f.e.) or will ask where to save it or it will ask what of the above to do.
Adding htmlentities() around strings with <, > characters should fix your problem:
$fdf = '%FDF-1.2
1 0 obj<</FDF<< /Fields[';
$fields = "";
foreach($dataContainer as $data)
{
if(array_key_exists($data['fieldname'], $this->fieldSet))
{
$field = '('.$data['fieldname'].')';
$value = '('.$data['content'].')';
$fields.='<</T'.$field.'/V'.$value.'>>';
echo $fields." ".$data['fieldname']."<br />";
}
}
$fdf.= $fields;
$fdf.= '] >> >>
endobj
trailer
<</Root 1 0 R>>
%%EOF';
$fdf = htmlentities( $fdf ); // Adding it here would make sure every <, > is replaced
