    Description

    Although " http://framework.zend.com/manual/en/… " states :

    "Zend recommends the most current release of PHP [...], and currently supports PHP 5.2.4 or later."

    it is not possible to use Zend_Pdf (Zend_Pdf_StringParser) with PHP 5.2.4.

    The problem comes from special escape sequences introduced only in PHP 5.2.5 :

    The "\f" escape sequence appears at several places in "Zend/Pdf/StringParser.php" and maybe elsewhere in the Zend_Pdf package.

    My current specific problem is "startxref" that is truncated to "startxre" because "\f" is handled as "f".

    I recommend using "\x0C" instead and still support PHP 5.2.4.

    Thank you!

    ZF-8791 solves te startxref issue, however errors relating this issue still exist.

    The error I get loading a pdf file is:

    An error occurred while processing a request (Zend_Pdf_Exception). Message: Argument must be numeric The error occurred in /var/www/versions/20110801-1205/library/Zend/Pdf/Element/Numeric.php at line 55. Trace: Zend_Pdf_Element_Numeric->__construct( 'alse' )

    Apparently 'F' in 'False' is cut.

    Proposed solution by Sylvain solves this issue. So replase all instances of \f by \x0C in Zend_Pdf_StringParser. The hack from #ZF-8791 that contains a phpversion check can be replaced.
