Assign same value to multiple variables at once?
...ns $a = ( $b = ( $c = $d ) )
PHP passes primitive types int, string, etc. by value and objects by reference by default.

$a = $b = $c;
$c = 5678;
//$a and $b = 1234; $c = 5678;
$c = new Object();
$c->property = 1234;
$a = $b = $c;
$c->property = 5678;
// $a,b,c->pro...

A semaphore is a generalization of a lock (or, the other way around, a lock is a special case of a semaphore). Usually, but not necessarily, spinlocks are only valid within one process whereas se...
What would cause an algorithm to have O(log log n) complexity?

Shrinking by a Square Root
As mentioned in the answer to the linked question, a common way for an algorithm to have time complexity O(log n) is for that algorithm to work by repeatedly cut the size of the input down by some constant fa...
