Error while printing invoice

Question

I've got a standard Magento 1.8.0.0 installation on Windows 7 using the BitNami Magento installation for XAMPP.

When I open the Sales -> Invoices screen and click on an invoice and then click on the orange Print button in the upper right hand corner of the screen I get the following error message inside the web browser:

Fatal error: Declaration of Zend_Pdf_FileParserDataSource_File::__construct() must be compatible with Zend_Pdf_FileParserDataSource::__construct() in C:\xampp\apps\magento\htdocs\lib\Zend\Pdf\FileParserDataSource\File.php on line 41

Anyone know why I am getting this and how to fix this?

Answer 1

Magento in versions before CE 1.9 / EE 1.14 is not compatible with PHP 5.4 out of the box, which causes this error.

Anyways, there is an official patch for this.

Answer 2

This an incompatibility issue between PHP Version 5.4.4 and zend Framwork .

Fixed it by change in this function lib/Zend/Pdf/FileParserDataSource.php.

change

abstract public function __construct();

to

abstract public function __construct($filePath);
