 * Hello from France
 * I’ve two plugins which use the same cmp() function :
 * So when i try to create an event , i get the following message :
    “ Fatal error:
   Cannot redeclare **cmp() (previously declared** in F:\inetpub\vhosts\xxxx.com\
   httpdocs\ddddd\wp-content\plugins\gcal-sidebar\gcal-sidebar.php:30) in F:\inetpub\
   vhosts\xxxx.com\httpdocs\ddddd\wp-content\plugins\countdown-timer\fergcorp_countdownTimer.
   php on line 1022 “
 * In gcal sidebar :
    “ _**function cmp($a, $b)** { if($a[‘startTime’] > $b[‘startTime’])
   return 1; if($a[‘startTime’] == $b[‘startTime’]) return 0; if($a[‘startTime’]
   < $b[‘startTime’]) return -1; }
 * In fercop :
    “ _/*Begin sorting events by time*/ **function cmp($adate, $bdate)**{
   if($adate < $bdate){ return -1; }else if($adate == $bdate){ return 0; }else{ 
   return 1;  “
 * Desactivation then activation of the plugin without succes .
 * How can i fix this ?
 * Many thanks,
 * Didier

 * Hello,
 * I’ve changed the name – In gcal sidebar – of the function cmp($a, $b) …
    with:
   function cmp**e**($a, $b) ,
 * and both the plugins work properly .
 * Is there a way to check such “identical naming ” evrythere in all the php files?

 * This is a bug. For various reasons, I thought this should not happen..but PHP
   is weird like that. It’s been fixed as of commit 9b65880968 and will be part 
   of the next release. Sorry for the inconvenience 🙁
