exec doesn't execute command if path contains whitespaces

Manoj Bhatt 2880 10 May 2013

When I do something like

exec("c:\\Program Files (x86)\\wkhtmltopdf\\wkhtmltopdf.exe --footer-center as http://bbc.co.uk c:\\test2.pdf",$output);

nothing happens. File exists and the following line returns 1.

echo file_exists("c:\\Program Files (x86)\\wkhtmltopdf\\wkhtmltopdf.exe");

If I change it

exec("d:\\wkhtmltopdf\\wkhtmltopdf.exe --footer-center as http://bbc.co.uk c:\\test2.pdf",$output);

works fine. Can that be fixed?

Thanks in advance!

Hi Manoj!

You need to quote your executable's path or escape the white space. Either:

exec("c:\\Program^ Files^ (x86)\\wkhtmltopdf\\wkhtmltopdf.exe --footer-center as http://bbc.co.uk c:\\test2.pdf",$output);

exec("\"c:\\Program Files (x86)\\wkhtmltopdf\\wkhtmltopdf.exe\" --footer-center as http://bbc.co.uk c:\\test2.pdf",$output);

will work.
