In PHP, we can compare numbers using comparison operators. The comparison operators include:
- Equal to ( == ) - This operator checks if two values are equal.
- Not Equal to ( != ) - This operator checks if two values are not equal.
- Greater than ( > ) - This operator checks if a value is greater than another value.
- Lesser than ( < ) - This operator checks if a value is lesser than another value.
- Greater than or equal to ( >= ) - This operator checks if a value is greater than or equal to another value.
- Lesser than or equal to ( <= ) - This operator checks if a value is lesser than or equal to another value.
Examples are:
$a = 10;
$b = 20;
//Equal to operator
if($a == $b){
echo "Number a is equal to number b";
} else {
echo "Number a is not equal to number b";
}
//Greater than operator
if($a > $b){
echo "Number a is greater than number b";
} else {
echo "Number a is not greater than number b";
}
//Lesser than or equal to operator
if($a <= $b){
echo "Number a is lesser than or equal to number b";
} else {
echo "Number a is not lesser than or equal to number b";
}
The output of the above program would be:
Number a is not equal to number b
Number a is not greater than number b
Number a is lesser than or equal to number b
