i have never use static variables inside of functions and likely never will.
go for static class variables instead :)
<?php
class foo{
public static $foobar = false;
public function bar(){
static $foobar=false;
if (self::$foobar === False){
self::$foobar='FUBeyondAllR';
echo self::$foobar . "\n";
}else{echo "already defined\n";}
}
}
$f=new foo();
$f->bar();
$f->bar();
foo::$foobar=false;
$f->bar();
?>
nathan@devel ~/working/www/siuConference $ php testScript.php
FUBeyondAllR
already defined
FUBeyondAllR
