Question

write a program in php to generate first 20 natural numbers?​

Answer 1

for( $i=1; $i<=20; $i++ )

{

echo $i;

echo "<br>";

}

PHP for loop is same as C program.

$i is the variable which will get initialized to 1 in the beginning of for loop.

It loops until $i becomes equal to 20. (First 20 natural numbers).

First Echo statement prints the value of $1.

Second Echo prints the new line

The loop increments the $1 value to next level.

Above program prints first 20 natural numbers.
