These are called (well, one name for it), is ternary operator. It's not
PHP specific and a search on google will find some results. Regarding
PHP, brief discussion (with examples) can be found at the following
locations :
http://www.php.net/manual/language.expressions.php
same from :
header(Location: .(empty($SESSION[wantsurl]) ? $CFG-wwwroot :
$SESSION[wantsurl]));
Exit;
or, if not readable enough then:
if(empty($SESSION[wantsurl])) {
$goto = $CFG-wwwroot;
}
else {
$goto = $SESSION[wantsurl];
}
header(Location: $goto);
