Here's something uncommon:
How to make one else statement for two nested if conditions?
aka: how to make one else for two ifs.

By default people simply copy & paste code in else like that:
<?php
if ( is_object($times)){
 if ((float)$times->getTime()>0){
    //code
 }else{
     //else code Alpha
 }
}else{
    //duplicated else code Alpha
}
?>

but it's much better and easier to simply use one condition inside of another, like that:

<?php
if ( is_object($times) ? (float)$times->getTime()>0 : false){
    //put here your code that gonna be executed if $times is an object and if $times->getTime() is greater than zero
    //condition is the same as:
    //if (is_object($times)){
    //    if ((float)$times->getTime()>0){
    //            //code
    //    }
    //}
}else{
    //put here your else statement for conditions above
}
?>

I don't get it... there seem to be only two different sets of instructions, exactly one of which has to be executed.... this is independent of the number of conditions that have to be checked because you can do the following:
if(condition1 && condition2)
do this
else
do this other thing

Seems to be me like what you did there is needless, or am I missing something?

@bibiki, you are right for simpler conditions what you have said is true. But for some unique cases where you need something equivalent to switch-case construct, where you have multiple cases but ONE default condition, then this type of situation requires same code in multiple else conditions. So this is just another method if someone has this unique requirement
