<?phpfor($i=0;$i<=10;$i++){$a=$i;echo $a."<br>";}echo $i?>

i got output as

01234567891011

1) question 1) why am i getting 11 after

echo $i

this outside for loop;question 2) I got the same out put when I write

$i+=1

so is can $i++ replace Si+=1 and viceversa

1) when $i is 10 it got incrementd by $i++ so it become 11 and after tha it check the c0nditi0n $i<=10 and it returns false so it come out of lo0p. But at that time $i is still 11 so when you echo it outside of l0op it shows u 112) $i++ and i+=1 is same
