I had a doubt if any services need to be restarted if port no in /etc/services in an RHEL setup is changed. For eg, the port no of 443 for SSL may need to be changed.

LEARN ABOUT PHP
system
SYSTEM(3) 1 SYSTEM(3)system - Execute an external program and display the outputSYNOPSIS
string system (string $command, [int &$return_var])
DESCRIPTION system(3) is just like the C version of the function in that it executes the given $command and outputs the result.
The system(3) call also tries to automatically flush the web server's output buffer after each line of output if PHP is running as a
server module.
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.
PARAMETERS
o $command
- The command that will be executed.
o $return_var
- If the $return_var argument is present, then the return status of the executed command will be written to this variable.
RETURN VALUES
Returns the last line of the command output on success, and FALSE on failure.
EXAMPLES
Example #1
system(3) example
<?php
echo '<pre>';
// Outputs all the result of shellcommand "ls", and returns
// the last output line into $last_line. Stores the return value
// of the shell command in $retval.
$last_line = system('ls', $retval);
// Printing additional info
echo '
</pre>
<hr />Last line of the output: ' . $last_line . '
<hr />Return value: ' . $retval;
?>
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.
