[SOLVED] How do you add +1 in this part?

[willdk]

if you have

$min = "10";
$max = "20";
...
rand($min,$max)

 

How do you add +1 to the value of the rand output?

rand($min,$max) +1

How do you add +1 to the value of the rand output?

rand($min,$max) +1

I would use the if statement.

<?php
$min = 10;
$max = 20;

$num = rand($min, $max);
$num++;

?>

I don't understand why I have to use 'if' ???

 

I make this smaller...

$random = rand($min,$max);

 

Then I have a value between 10 and 20 for $random. So if the value is 15 then I want to have the same value to be increased by 1 ($random + 1). I'm a newbie so don't shoot me if I'm wrong...

<?php
$min = 10;
$max = 20;

$num = rand($min, $max);
$num++;

?>

 

I tried this code before but I get the same value

<?php
$min = "10";
$max = "20";
$random = rand($min,$max);
echo $random.' and '.$random++ ;
?>

 

10 and 10

16 and 16

Use ++$var If you echo the var immediately.

 

<?php
$var = 1;
echo $var++; //returns 1 but after the echo it has INT 2 as value

$var = 1;
echo ++$var; //returns 2
?>

Thanks Bjorn, But it was not what I was looking for

 

I found the solution after trying and trying

$random + 1

 

gr.

[BjornR_1989]

$var + 1;

is exactly the same as

$var++;

 

Btw, don't use

$min = "10";
$max = "20";

for integers, use

$min = 10;
$max = 20;

[willdk]

Btw, don't use

$min = "10";
$max = "20";

for integers, use

$min = 10;
$max = 20;

 

Thanks for the tip

 

$var + 1;

is exactly the same as

$var++;

 

my working code

$random = rand($min,$max);
$irandom = $random + 1;

 

When I use $random++ the value decreases (-1)

[balistic]

why not just use

 

$random = rand($min,$max)+1;

[willdk]

why not just use

 

$random = rand($min,$max)+1;

Works indeed. thx. Then I don't need that extra line '$irandom...'.
