for every number, add +50

[newb]

i have a number string which is any random integer of 1-10.

 

how can i make it so that if the string turns out to be 5, there will be 50 added on for every number under it. for example:

 

$string = '5';

 

1: +0

2: +50

3: +50

4: +50

5: +50

 

etc etc..

 

can anyone help?

Could you show the actual numbers inside 0:, 1:, 2:, etc.?

 

Also, what would those numbers be if the number string was not 5 but rather 8?

yes the actual numbers would be

 

1: 50

2: 100

3: 150

4: 200

5: 250

 

Also, what would those numbers be if the number string was not 5 but rather 8?

 

they would just continue to add on

So you want a loop that loops X times (5 or 8 in our story so far), and prints out 50, 100, etc?

 

foreach ($i = 1; $i <= $number_of_values; $i++) echo $i * 50;

 

I renamed $string to $number_of_values, I think it is a better name.

<?php

$value = 8;
for($i = 1; $i <= $values; $i++) {
echo $i . ':';
echo $i * 50;
echo '<br />';
}
?>

 

hope this what u wants

ok im getting close: the problem is that it is adding +50 on the first value which is 1 (i dont want this)

 

anyway to fix this? i just want it to add +50 to the all the other values except the first

 

so it should be as.

 

1. +0

2. +50

3. +50

 

etc etc.

<?php

$values = 8;
for($i = 1; $i <= $values; $i++) {
echo $i . ':';
if($i == 1) {
echo $i * 0;
} else {
echo ($i * 50) - 50;
}
echo '<br />';
}
?>

works perfectly, thanks!

Here's a shorter version with the same results:

<?php foreach ($i = 0; $i < $number_of_values; $i++) echo "$i: " . $i * 50 . '<br />';
