php for i--

In PHP, the for loop can be used to iterate over a range of values in reverse order. To iterate from a certain value i and decrement it by 1 in each iteration, you can use the following syntax:

for ($i = starting_value; $i >= ending_value; $i--) {
    // code to be executed in each iteration
}

Replace starting_value with the initial value of i, and ending_value with the final value at which the loop should stop. The loop will continue executing as long as i is greater than or equal to ending_value, and in each iteration, i will be decremented by 1.

Here's an example that demonstrates how to use the for loop in reverse order:

for ($i = 10; $i >= 1; $i--) {
    echo $i . " ";
}

This code will output the numbers from 10 to 1 in reverse order:

10 9 8 7 6 5 4 3 2 1
