[fw-general] Zend Framework 1.0.3 Problems with Zend_ Loader::isReadable($filename) and initial View Helpers

[SamBroker]

Hello together,

I experienced a problem with Zend_Loader in the new ZF release. With the new 
release ZF does not found the initial Viewhelpers. It searches first in the 
application\views\helpers and not in the Zend\View\Helper directory. I got 
following error message:

exception 'My_ErrorhandlerException' with message 
'fopen(..\application\views\helpers\Url.php) [<a 
href='function.fopen'>function.fopen</a>]: failed to open stream: No such file 
or directory' in D:\www\library\Zend\Loader.php:194

The problem seems to be related with the new Zend_Loader::isReadable($filename) 
method. If I replace the code of this method with the old code from the ZF 
v1.0.2 it works fine. I guess the problem is the @ before fopen, it does not 
suppress the error in E_ALL|E_STRICT mode. The function is_readable() was 
better, because it throws no error and returns only false or true.

// NEW CODE FROM ZF 1.0.3:
    public static function isReadable($filename)
    {
        if (!$fh = @fopen($filename, 'r', true)) {
            return false;
        }

        return true;
    }

// OLD CODE FROM ZF 1.0.2:
    public static function isReadable($filename)
    {
        if (@is_readable($filename)) {
            return true;
        }

        $path = get_include_path();
        $dirs = explode(PATH_SEPARATOR, $path);

        foreach ($dirs as $dir) {
            // No need to check against current dir -- already checked
            if ('.' == $dir) {
                continue;
            }

            if (@is_readable($dir . DIRECTORY_SEPARATOR . $filename)) {
                return true;
            }
        }

        return false;
    }



Best regards
Sascha
