How to get the previous value from incrementing variable in for loop?
- by Parth
In My last post I asked :
How to create dynamic incrementing variable using "for" loop in php? like wise: $track_1,$track_2,$track_3,$track_4..... so on....
whose answer I selected as
for($i = 0; $i < 10; $i++) {
$name = "track_$i";
$$name = 'hello';
}
and
for($i = 0; $i < 10; $i++) {
${'track_' . $i} = 'val'
}
Now, What If I need the Value of variable previous than the current variable?
