Excel Reader Problems

[adnan1983]

Hi,

I keep getting these errors for at least 500 lines. Not sure what
exactly is wrong? The same exact script works just fine on my other
server.

I am using excelreader http://sourceforge.net/projects/phpexcelreader

Any help would be appreciated.

Its just a guess without any code.

Sorry, I just downloaded the class from sourceforge and uploaded the files. Which works on my server but not on the other.

Is there any alternate method of reading excel files? I am on a linux server.

Save it as a CSV file and use a fgetcsv() (http://www.php.net/fgetcsv) loop.

[adnan1983]

Not sure if the client is going to be comfortable with that, but I guess that is the solution at this point.

One server could just be suppressing the NOTICE errors on the screen.
Is the script actually failing out?

Probably one server has a 64 bit processor. The GetInt4d bit shift doesn't work with 64 bit processors.

Andreas Rehm hacked it to ensure correct result of the <<24 block on 32 and 64bit systems, just replace the code of the GetInt4d function with the following:

$_or_24 = ord($data[$pos+3]);

if ($_or_24>=128)
$_ord_24 = -abs((256-$_or_24) << 24);
else
$_ord_24 = ($_or_24&127) << 24;

return ord($data[$pos]) | (ord($data[$pos+1]) << 8) | (ord($data[$pos+2]) << 16) | $_ord_24;
