* trigger the error with the PHP trigger_error() function (you can silence
|
|

|
* Example usage:
|
|
* if (!@System::rm('-r file1 dir1')) {
|
|
* print "could not delete file1 or dir1";
|
|
* }
|
|
*
|

* In case you need to to pass file names with spaces,
|
|
* pass the params as an array:
|
|
*
|
|
* System::rm(array('-r', $file1, $dir1));
