I have a problem with php system() function output. So here goes the code:
system("c:\\Dev-Cpp\\bin\\g++.exe c:\\wamp\\www\\hello.cpp -O3 -o c:\\wamp\\www\\hello.exe", $output);
echo $output;
So if my hello.cpp does compile I get 0, if it doesn't I get 1.
If I run the same thing from CMD instead of giving just 1 it gives me full error.
How can I get the full error with php system() function?
You are only catching the return code of the program, which is normally an integer where 0 means 'success' and anything else is an error code.
If you want to catch the actual output of the program (i.e. STDOUT and/or STDERR) You need to do one of these things:
system():$command = "c:\\Dev-Cpp\\bin\\g++.exe c:\\wamp\\www\\hello.cpp -O3 -o c:\\wamp\\www\\hello.exe"; ob_start(); system($command, $returnCode); $output = ob_get_clean();
exec(), shell_exec() or backticks:exec($command, $output, $returnCode); // ...or... $output = shell_exec($command); // ...or... $output = `$command`;
If you want to catch the output of STDERR (which I suspect you do), you may need to add 2>&1 to the end of your command string.
Alternatively, you may want to look at proc_open(), which is more complicated but can give you finer-grained control over the child process and how it executes/passes data back to you.
