How can I determine using PHP code that, for example, I have a variable that has a value

A random value?
If you want a random value, try
<?php
$value = mt_rand($min, $max);
mt_rand() will run a bit more random if you are using many random numbers in a row, or if you might ever execute the script more than once a second. In general, you should use mt_rand() over rand() if there is any doubt.
Do you mean like:
$val1 = rand( 1, 10 ); // gives one integer between 1 and 10
$val2 = rand( 20, 40 ) ; // gives one integer between 20 and 40
or perhaps:
$range = range( 1, 10 ); // gives array( 1, 2, ..., 10 );
$range2 = range( 20, 40 ); // gives array( 20, 21, ..., 40 );
or maybe:
$truth1 = $val >= 1 && $val <= 10; // true if 1 <= x <= 10
$truth2 = $val >= 20 && $val <= 40; // true if 20 <= x <= 40
suppose you wanted:
$in_range = ( $val > 1 && $val < 10 ) || ( $val > 20 && $val < 40 ); // true if 1 < x < 10 OR 20 < x < 40
Guessing from the tag 'operand' you want to check a value?
$myValue = 5;
$minValue = 1;
$maxValue = 10;
if ($myValue >= $minValue && $myValue <= $maxValue) {
//do something
}
if (($value >= 1 && $value <= 10) || ($value >= 20 && $value <= 40)) {
// A value between 1 to 10, or 20 to 40.
}
You can do this:
if(in_array($value, range(1, 10)) || in_array($value, range(20, 40))) {
# enter code here
}
returns true if subject is between low and high (inclusive)
$between = function( $low, $high, $subject ) {
if( $subject < $low ) return false;
if( $subject > $high ) return false;
return true;
};
if( $between( 0, 100, $givenNumber )) {
// do whatever...
}
looks cleaner to me
If you just want to check the value is in Range, use this:
MIN_VALUE = 1;
MAX_VALUE = 100;
$customValue = min(MAX_VALUE,max(MIN_VALUE,$customValue)));
Try This
if (($val >= 1 && $val <= 10) || ($val >= 20 && $val <= 40))
This will return the value between 1 to 10 & 20 to 40.
