Question

Answer 1

+1 A:

for ($i = 0; $i < LENGTH_GOES_HERE; $i++) { ... }

or

foreach (range(0, LENGTH_GOES_HERE - 1) as $i) { ... }, cf. range().

the `foreach` line should use `LENGTH_GOES_HERE - 1`

@intgr I'm offsetting on the `low` instead.

jensgram 2009-11-25 14:45:36

@intgr But you're right, I see. We want `$i` to have the same values as in the question :)

Answer 2

+6 A:

Straight from the docs:

foreach (range(0, 12) as $number) {
    echo $number;
}

One caveat: Python's `range(0, 13)` or `range(13)` is equivalent to PHP's `range(0, 12)`

Answer 3

+1 A:

There is a range function in php, you can use like this.

foreach( range(0,10) as $y){
    //do something
}

but unlike python, you have to pass 2 parameters, range(10) will not work.

Answer 4

+1 A:

Try this:

// Generates the digits in base 10.
// array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
foreach (range(0, 9) as $number) {
    echo $number;
}

Answer 5

+3 A:

Old fashioned for loops:

for ($i = 0; $i < length; $i++) {
    // ...
}

Or foreach using the range function:

foreach (range(1, 10) as $i) {
    // ...
}

Is there something like for i in range(length) in PHP?
