Can somebody explain me a php code please?

Question

The given code is:

$x=1;
While($x<10){
Echo $x;
$x=$x + 3;
}

The result is 147.
All i want to know is the steps to get to that result.

Thank you

Answer 1

In first iteration x value is 1 , hence while condition stands true and print 1 and increase x value by 3 means now x value is 4.

Again condition stands true , it prints 4 and increase x value by 3 means now x value is 7.

Again condition stands true , it prints 7 and increase x value by 3 means now x value is 10.

Now 10 < 10 stands false and hence output will be

147
