I have trouble understanding the meaning of the return_var in PHP.
I read that it is used in order to inform us if a PHP command has been executed.
I use system commands in PHP (like 'system', 'shell_exec' etc) and I can't find anywhere a list of the return_vars.
I mean that 0 is for 'OK, the command was executed'.
What does 1 stand for???
I execute a system command , I don't get any result, and if I ask PHP for the return_var, it says '1'.
Where could I find more info as to what return_var=1 means?
