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. ---- Server IP: 195.221.21.36 Probable Submitter: 82.126.126.227 ---- Manual Page -- http://www.php.net/manual/en/function.system.php Edit -- https://master.php.net/note/edit/102399 Del: integrated -- https://master.php.net/note/delete/102399/integrated Del: useless -- https://master.php.net/note/delete/102399/useless Del: bad code -- https://master.php.net/note/delete/102399/bad+code Del: spam -- https://master.php.net/note/delete/102399/spam Del: non-english -- https://master.php.net/note/delete/102399/non-english Del: in docs -- https://master.php.net/note/delete/102399/in+docs Del: other reasons-- https://master.php.net/note/delete/102399 Reject -- https://master.php.net/note/reject/102399 Search -- https://master.php.net/manage/user-notes.php
