Static variables.

$kartas is assigned every time and destroyed after end of unction.
<?

function test(){

$kartas++;
echo "cia yra $kartas iskvietimo kartas <br>"; //nieko gero

}

test();//1
test();//1
test();//1

?>
If you want to retain the value of a variable between one call to a function and the next, you can declare it as static. And as part of the initial declaration, you can assign a starting value to it. This allows you to test whether you're calling a function for the first time, or for a subsequent time:
<?

function test1(){

static $kartas = 0;
$kartas++;
echo "cia yra $kartas iskvietimo kartas <br>"; //nieko gero

if ($kartas>=3) echo "ir t.t.<br>";
$kartas++;

}

test1();//1
test1();//2
test1();//3

?>
