How to Print Even Numbers in PHP (1 to 100)

Printing even numbers in PHP is a basic programming task that helps beginners understand loops and number operations. There are different methods to achieve this, but one of the simplest ways is by using a for loop.
Even numbers are numbers that are divisible by 2, such as 2, 4, 6, and so on. In this example, we will print even numbers between 1 and 100.
Method 1: Using For Loop
In this method, we use a for loop to print even numbers between 1 to 100. The loop starts from 2, which is the first even number. Then, instead of increasing by 1, the loop increments by 2 each time. This ensures that only even numbers are printed.
PHP Code Example
<?php
echo "Even numbers between 1 to 100 :- ";
for ($j = 2; $j <= 100; $j += 2){
echo $j . ", ";
}
?>
|
Explanation
- The loop starts at 2 (first even number)
- The condition $j <= 100 ensures numbers stay within range
- The increment $j += 2 skips odd numbers
- Each number is printed with a comma for readability
Conclusion
Using a for loop is one of the easiest ways to print even numbers in PHP. This method is efficient and avoids unnecessary checks, making it ideal for beginners learning PHP programming.
