note 102399 added to function.system

Just a remark about a the fact that when you want use a variable in your system function, yous maybe find useful to call for trim() function too.
As exemple, let's take a file '/etc/config.cfg' containing the following lines :
EXEC=/usr/local/bin/enviro.sh
DIR=/home/fredmj
then you'll have to use trim() like that :

<?php
$CONFIGFILE = "/etc/config.cfg";
$DATACONFIG = file($CONFIGFILE);
foreach ($DATACONFIG as $line) {
$data = explode ('=',$line);
  switch ($data[0]) {
  case EXEC:
    $EXEC=$data[1];
  break;
   }
}

system(trim($EXEC)." --help");
?>

... in order to take into account the ' --help' argument. If not, the CR character will cut off any text after your $EXEC variable.
