In php, how can I make sure that static variables declared in a function will not be re-triggered whenever a function is called?

It seems that the static variable declared in the function is re-triggered whenever the function is called, how can I use this function so that re-calling the function reuses the static parameter?

I defined the testStatic function in static.php

here is static.php:

<?php
function testStatic()
{
    static $staticV = 0;
    echo $staticV;
    $staticV;
}
?>

I call "testStatic" from index.php

here index.php:

<?php include "./static.php";?>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"   "http://www.w3c.org/TR/html4/strict.dtd">
<?php
testStatic();
?>

index.php , testStatic '0', index.php. testStatic '0'. , 'staticV' 'testStatic' , index.php.

Remember that if you want this number to be in a sequence not for a specific user, but for all users you will have to do additional work to handle synchronization.
