Question

When i write code i have to use loops e.g.

$six = 6;
for ($i = $six; $i > 1; $i--) {
   echo $i."<br>";
}

outputs

6
5
4
3
2

i need it to output 1 as well i know i can do for ($i = 6; $i >= 1; $i--)

or
for ($i = $six+1; $i > 1; $i--) in evaluation but its confusing so muchg!
in fact i always confused when using for statement.

EDIT: its confusing because i dont like to think backwards.. id like to run loop not while condition $six > 1 is true, but rather before condition like $six = 1 is meet.

the opposite way i guess

loop_before ($six==1) {
   echo $six.<br />;
   $six--;
}

well even this one wont output 654321… guess i just need to go back to school.
got to do

loop_before ($six<1) {
   echo $six.<br />;
   $six--;
}

This confusion may not be only for for() statement but for other types of loop. You can use $six >= 1 or $six > 0

Example 1

$six = 6;
do {
    echo $six . "<br>";
    $six --;
} while ( $six >= 1 );

Example 2

$six = 6;
for($i = $six; $i >= 1; $i --) {
    echo $i . "<br>";
}

Example 3

$six = 6;
while ( $six >= 1 ) {
    echo $six . "<br>";
    $six --;
}

Lastly you might decide not to even use any default PHP loop

$six = 6;
__loop($six);

function __loop($x) {
    echo $x . "<br>";
    $x --;
    ($x < 1) ? $x : __loop($x);
}

They would all return the same thing
