# While, for, and do-while

Hey there I would like to make a
sum of the integers from 1 to 100 using the three different loop
statements: while, for, and do-while.

any help would be appreciated.

Sure sounds like it. Usually you would just pick one method and use it, not asking for 3 possible ways to do the same task.

\$i = 0;
\$sum = 0;
while(\$i < 101){
\$sum += \$i;
\$i+=1;
}

You can wrap this into a function and return \$sum or just echo \$sum

\$i = 0;
\$sum = 0;
do{
\$sum += \$i;
\$i+=1;

} while(\$i<101);

I agree with the above. It sounds like you’re seeking answers to your homework. Whats the point studying a IT related subject if you’re not interested? - Some of us can’t even afford the opportunity of an education in IT.

Despite that, I still find myself wanting to help.
Here are 3 examples:

``````
//While Loop
\$I = 0;
while (\$I < 101)
{
\$I = \$I +1;
print "\$I <br />";
}

``````
``````
//For loop
for (\$I = 0; \$I < 101; \$I++)
{
//Do something else here - \$I's incrementation is dealt with automatically
print \$I .'<br />';
}

``````
``````
//Do-While Loop
\$I = 0;
do
{
print "\$I<br />";
}
while (\$I < 101);

``````

Of course a quick google for php loops would of found you examples on php.net

thanks a lot guys. Tried a few attempts before asking you people.
