<?php
for($i=10;$i>0;$i--){
echo $i.'<br>';
}

then yo have this:
<?php
$v=10;
do{
echo $v.'<br>';
}while(--$v);
/*
while(--$v) : 10...1 , when $v==0 stops
*/
?>
(PHP 4, PHP 5, PHP 7, PHP 8)
while loops are the simplest type of loop in
PHP. They behave just like their C counterparts. The basic form
of a while statement is:
while (expr)
statement
The meaning of a while statement is simple. It
tells PHP to execute the nested statement(s) repeatedly, as long
as the while expression evaluates to
true. The value of the expression is checked
each time at the beginning of the loop, so even if this value
changes during the execution of the nested statement(s), execution
will not stop until the end of the iteration (each time PHP runs
the statements in the loop is one iteration). If the
while expression evaluates to
false from the very beginning, the nested
statement(s) won't even be run once.
Like with the if statement, you can group
multiple statements within the same while loop
by surrounding a group of statements with curly braces, or by
using the alternate syntax:
while (expr):
statement
...
endwhile;
The following examples are identical, and both print the numbers 1 through 10:
<?php
/* example 1 */
$i = 1;
while ($i <= 10) {
echo $i++; /* the printed value would be
$i before the increment
(post-increment) */
}
/* example 2 */
$i = 1;
while ($i <= 10):
echo $i;
$i++;
endwhile;

}while(--$v);
/*

?>While loops don't require a code block (statement).
<?php
while( ++$i < 10 ); // look ma, no brackets!
echo $i; // 10
?>The example below displays the numbers from 1 to 5:
<?php
$x = 1;
while($x <= 5) {
echo "The number is: $x <br>";
$x++;
}
?>
This example counts to 100 by tens:
<?php
$x = 0;
while($x <= 100) {
echo "The number is: $x <br>";
$x+=10;
}
?>
