What is the difference between 'for' and 'since'?

Answer 1

for is a standard loop

foreach allows you to automatically loop through an array

for (i = 0; i < somevalue; i++) {}

vs

$arr = array(1, 2 , 3 , 4);

foreach ($arr as &$value) { $value = $value *2; }

(Note: The & means reference the original, which means this function is changing the array on the fly)

Answer 2

'During' denotes a general period of time....For example..I played the guitar during my lunch time which could me for 20 mins or 1 hour. 'For' denotes a specific period of time. For example I played the guitar for 30 mins.

Answer 3

It depends on the sentence you use. For example, ''This gift is FOR Nancey''. or, ''I'm giving this TO Nancey''.

Answer 4

When they means "because", none.

But as time indicator "for" is about how long a period occur while "since" is more about when a period starts.
