# PHP Program to Check Even Number

You are Here:

## What are Even Numbers?

An integer (never a fraction) that can be divided exactly by 2. For example, 10 is an even number, i.e., 10 % 2 = 0.

Note: % is a Modulus (Division Remainder) operator, it finds the remainder after division of one number by another. Please check our Arithmetic Operators for more details.

Tips: It is recommended to use our online Even Numbers calculator for better understanding.

## Using For Loop

In the following example, we will find all the Even Numbers between 10 and 25 using for loop.

### Example

PHP Compiler
<?php \$start = 10; \$end = 25; echo "Even numbers between \$start and \$end: <br>"; for(\$start=\$start; \$start<=\$end; \$start++) { if(\$start % 2 == 0) echo "\$start "; } ?>

### Output

Even numbers between 10 and 25: 10 12 14 16 18 20 22 24

## Using While Loop

In the following example, we will find all the Even Numbers between 10 and 25 using while loop.

### Example

PHP Compiler
<?php \$start = 10; \$end = 25; echo "Even numbers between \$start and \$end: <br>"; while(\$start <= \$end) { if(\$start % 2 == 0) echo "\$start "; \$start++; } ?>

### Output

Even numbers between 10 and 25: 10 12 14 16 18 20 22 24

## Using do while Loop

In the following example, we will find all the Even Numbers between 10 and 25 using do while loop.

### Example

PHP Compiler
<?php \$start = 10; \$end = 25; echo "Even numbers between \$start and \$end: <br>"; do{ if(\$start % 2 == 0) echo "\$start "; \$start++; }while(\$start <= \$end); ?>

### Output

Even numbers between 10 and 25: 10 12 14 16 18 20 22 24
