shell_exec() not executing pdftotext command

Question

I installed the required library and its working in terminal but not in my php file. My code is :

$mypdf = shell_exec('/usr/local/bin/pdftotext test.pdf test.txt');
echo $mypdf;

If I execute this command /usr/local/bin/pdftotext test.pdf test.txt in terminal it works fine.

I also write my code this type :

shell_exec('/usr/local/bin/pdftotext test.pdf test.txt');
$mypdf = file_get_contents("test.txt");
echo $mypdf;

In Error Log the message is :

/usr/local/bin/pdftotext: /opt/lampp/lib/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/i386-linux-gnu/libstdc++.so.6)

Answer 1

I think you have some trouble with a dependency. Check your error.log. Find out which file is missing and add it to the path environment variable of your php installation.

Answer 2

My guess would be that you're expecting $mypdf to contain the PDF document instead of the return value of the executed command. If you're trying to print out 'test.txt', then you'll need to load it up and print it.

Answer 3

Issue was: /usr/local/bin/pdftotext: /opt/lampp/lib/libgcc_s.so.1: version 'GCC_4.2.0' not found (required by /usr/lib/i386-linux-gnu/libstdc++.so.6)

And the solution was to rename /opt/lampp/lib/libgcc_s.so.1 to libgcc_s.so.1.bak and solves my problem. But confusion is that what was the issue in it :P
