php system command with output and return code

Question

I am looking for something in php that would given output (raw) of a system command in a variable along with the return code.

exec does this, but the output is in array and hence the data returned is not proper(as \n comes in new index).
system outputs the data in the output stream and not in a variable.
shell_exec does not give the return value but gives raw data.

Can't you just implode() the result from exec() to turn it into a string? — JJJ

Sounds like you're looking for output buffering:

ob_start();
system($command, $returnCode);
$output = ob_get_clean();

This should preserve all white-space characters at the end of each output line (exec as you wrote destroys these, so implode would not be an option).

Alternatively, you can open a process and aquire the pipes (standard output, STDOUT) and read the output out of these. But it's more complicated (but gives you more options). See proc_open.
