help with php operator

Hi

 

Ok, so I pick a random value 23 for example and I want this value to be in between two other values.

E.g. if 23 is in between 20 and 30, then continue otherwise die.

 

How can I do this?

What would the range of the random value being picked be? You can use rand to pick random numbers.

This for example:

 

$userscoreratio($userID) = 23%

$ds['ratio_low'] = 20%

$ds['ratio_high'] = 30%

 

if($userscoreratio($userID) >= $ds['ratio_low'] && =< $ds['ratio_high'])

 

Is this the correct if statement for what I want to achieve?

[Alex]

There are some problems with that. I think you want something like this:

 

$lower = 20;
$higher = 30;
$var = 23;

if($var >= $lower && $var <= $higher) {
    // ...
}

Ok, so this IF statement

 

if(($ds['ratio_low'] || $ds['ratio_high']) && userscoreratio($userID) >= $ds['ratio_low'] && userscoreratio($userID) <= $ds['ratio_low'])

 

Means if $ds['ratio_low'] or $ds['ratio_high'] is not 0 and userscoreratio (23%) is greater or equal to $ds['ratio_low'] (20%) AND userscoreratio (23%) is equal or lesser than $ds['ratio_high'] (30%) ??

 

Thanks for help.

[Alex]

Yes, but don't you want it to be less than or equal to $ds['ratio_high']?

[karimali831]

Yeah, I changed my post before your reply.

 

-- Thanks.

Something that did not work for me, not sure why:

 

elseif(($ds['ratio_low'] || $ds['ratio_high']) && clanscoreratio($clanID) < $ds['ratio_low'] || clanscoreratio($clanID) > $ds['ratio_high'])

 

I had to use

 

elseif(($ds['ratio_low'] || $ds['ratio_high']) AND clanscoreratio($clanID) < $ds['ratio_low'] || clanscoreratio($clanID) > $ds['ratio_high'])

 

I thought "AND" and "&&" operate exackly the same? why doesn't "&& clanscoreratio..." work and "AND clanscoreratio.." does work?
