Static variable in php is not working as expected in a recursive function

Question

I am using static variable in php. Ideally this should display 1 to 10.

But it is not. Why is it so ?

test(10);
function test($a)
{
    static $count = 0;

    $count++;
    echo $count;
    if ($count < $a) {
        echo 'in if ' . $count;
        test($count);
    }

}

Answer 1

You have wrong variable in your if. If you debug it you would see that function triggers only twice instead of 10.

change

if ($count < $a) {
    echo 'in if ' . $count;
    test($count);
}

to

if ($count < $a) {
    echo 'in if ' . $count;
    test($a);
}

Answer 2

Use this if you want to print 1 to 10

function test($a)
{
    static $count = 0;

    $count++;
    echo $count."====".$a;
    if ($count < $a) {
        echo 'in if ' . $count;
        test($a);
    }

}
