Hi, I am integrating KoolReport Pro into our system, and I was wondering if there was a simple way to set the pdf output as a variable or base64 encode it to be returned as a json object. Fore example, the sakila_rental example uses the following code -

$report->run()
->export('SakilaRentalPdf')
->pdf(array(
    "format"=>"A4", 
    "orientation"=>"portrait"))
->toBrowser("sakila_rental.pdf");

What I'd like to do is -

$resultOutput = $report
->run()
->export('SakilaRentalPdf')
->pdf(array( 
    "format"=>"A4", 
    "orientation"=>"portrait"
))->toBrowser("sakila_rental.pdf");
$encodedResult = base64_encode($resultOutput);

Any help with this is much appreciated.

Update: have this sorted, added a custom function to "File" package.

To those who need the same functionality, I added the following to koolreports/packages/export/File.php. It would require you have the PDF export package.

public function toBase64() {
    $source = realpath($this->path);
    $file = @fopen($source,"rb");
    if ($file) {
        $result = file_get_contents($source);
        @fclose($file);
        return base64_encode($result);
    }
}

It can be assigned to a variable as follows

$base64PDF = $report
->export('SakilaRentalPdf')
->pdf(array(
    "format"=>"A4",
    "orientation"=>"portrait"
))
->toBase64();

//echo out the base64 string or json here also
echo $base64PDF;
