FYI if you want the output of that command to be put at the end of the file use a forward tick `` in place of the double quotes "".

EXEC(3) 1 EXEC(3)
exec - Execute an external program
SYNOPSIS
string exec (string $command, [array &$output], [int &$return_var])
DESCRIPTION
exec(3) executes the given $command.
PARAMETERS
o $command
- The command that will be executed.
o $output
- If the $output argument is present, then the specified array will be filled with every line of output from the command. Trailing
whitespace, such as
, is not included in this array. Note that if the array already contains some elements, exec(3) will append
to the end of the array. If you do not want the function to append elements, call unset(3) on the array before passing it to
exec(3).
o $return_var
- If the $return_var argument is present along with the $output argument, then the return status of the executed command will be
written to this variable.
RETURN VALUES
The last line from the result of the command. If you need to execute a command and have all the data from the command passed directly back
without any interference, use the passthru(3) function.
To get the output of the executed command, be sure to set and use the $output parameter.
EXAMPLES
Example #1
An exec(3) example
<?php
// outputs the username that owns the running php/httpd process
// (on a system with the "whoami" executable in the path)
echo exec('whoami');
?>
NOTES
Warning
When allowing user-supplied data to be passed to this function, use escapeshellarg(3) or escapeshellcmd(3) to ensure that users can-
not trick the system into executing arbitrary commands.
Note
If a program is started with this function, in order for it to continue running in the background, the output of the program must be
redirected to a file or another output stream. Failing to do so will cause PHP to hang until the execution of the program ends.
Note
When safe mode is enabled, you can only execute files within the safe_mode_exec_dir. For practical reasons, it is currently not
allowed to have .. components in the path to the executable.
Warning
With safe mode enabled, the command string is escaped with escapeshellcmd(3). Thus, echo y | echo x becomes echo y | echo x.
