PHP Loop Help

Question

Write a small program (Code) in PHP language using for loop which prints from 1 to 100.

Answer 1

The code:

for($i = 1; $i <= 100; $i++){

// if avoidable, don't echo here

echo "$i <br>";

}

Explanation:

A for loop has three commands. The first one is assigning a value to the iterator ($i = 1). The second is the condition. Here we declare that the iteration shall proceed as long as the condition of $i being smaller or equal to 100 is met ($i <= 100). The last command describes what the iterator should do after gong through the block. In our case, we increment ($i++) the iterator. Incrementing with "++" is the same as if you were to write "$i = $i +1"

In our code we use the iterator ($i) directly as output to represent the current value.
