How to put PHP variable with lower and higher value (min and max)

Question

Hello, everybody!

I wonder if there is the possibility of making a variable in PHP with a min and max numeral, for example:

$var = /a numeral greater than or equal to 10 OR a numeral less than or equal to 20/;

Is there any way to do this directly in the variable without having to use if or similar?

Thanks in advance. Thank you! : D

If you want a random number:

$var = rand( 10, 20 );

Handbook:

int rand ( int $min , int $max )

If you want to apply to an existing value

$var = max( min( $var, 20 ), 10 );

Handbook:

mixed min ( mixed $value1 , mixed $value2 [, mixed $... ] )
mixed max ( mixed $value1 , mixed $value2 [, mixed $... ] )
