Reading negative values from excel file using php

I need to read excel data. so i've used phpExcelReader . It worked great, but unfortunately it do开发者_运维问答esn't reading negative values in 64 bit architecture.

In 32 bit architecture it doesn't any problems in reading negative values. I don't know how to get around this issue? Any help will be greatly appreciated. Thanks!

Check the below link on this issue. May be this is what you are looking for, http://code.google.com/p/php-excel-reader/issues/detail?id=123 also http://code.google.com/p/php-excel-reader/issues/detail?id=28

Let me clarify this issue once again. Find the OLERead class (in my case in excel_reader2.php) and replace the bodies of both these two methods:

_GetInt4d() and GetInt4d()

with this code:

function GetInt4d($data, $pos) {
    $value = ord($data[$pos]) | (ord($data[$pos+1]) << 8) | (ord($data[$pos+2]) << 16) | (ord($data[$pos+3]) << 24);
    if ($value>=4294967294) {
        $value=-2;
    }
    return $value;
}

Now the class supports both the 32 and 64 bit OS architectures. I hope it is now clear and helps.
