This is a homework question, I'm not sure why people are just giving you an answer to copy-paste.

Achieving the sum of numbers 1..10 is pretty simple. You will need to initialise an empty int var before your loop, and for each iteration from 0 up to and including 10 you will add your int var to the current iteration.

For example:

sum = 0;

for num in range 1 to 10:
    sum = sum + num;

Using the for loop:

<?php

$sum = 0;

for($i = 1; $i <= 10; $i++){
  $sum += $i;
}

Using the foreach loop:

<?php

$sum = 0;

foreach(range(1,10) as $num){

  $sum += $num;

}

echo $sum; // prints 55

And disregarding your assignment, here is an easier way:

echo array_sum(range(1,10));

I would use a for loop.

$total = 0;

for($i = 1; $i <= 10; $i++){
  $total += $i;
}

<?php

$start = 0; // set the variable that will hold our total

for($i=1;$i<11;$i++){ // set a loop, read here: http://php.net/manual/en/control-structures.for.php for more info
  $start += $i; // add $i to our start value
}
echo $start; // display our final value
