I'm using PHP exec() in a script to merge PDF files with PDFTK.
From PHP docs: exec function says the second argument, if provided, will list each line from the console output. All I get is an empty array though.
Example of code being used:
exec(pdftk "file1.pdf" "file2.pdf" Merged_File.pdf, $output = array(), $result);
I can successfully get errors if I run the code in the console, but I'd like for my application to have access to the full text errors.
