Status: Open

Because this way local static variables can't be used eg. for caching
method
return values. I think it's a very important use case. I also don't
think that it
would cause severe bc issues.

Why? At most this is a (bc breaking) feature request. Function static
variables have always been tied only with the function itself.

Description:
------------
The inital value of a static variable in a non-static method should take
care
about the current instance. The initialization should be done when a
method of
the instance is called, and not only when the method is first called in
the
script. The local static variable should be interpreted as an object
variable
that is visible only in the declaring method.
Test script:
---------------
<?php
class StatTest {
function statvartest() {
static $var = 'initial';
echo $var."\n";
if ($var == 'initial') {
$var = 'changed';
}
}
}
$testA = new StatTest;
$testA->statvartest();
$testA->statvartest();
$testB = new StatTest;
$testB->statvartest();
$testB->statvartest();
Expected result:
----------------
initial
changed
initial
changed
Actual result:
--------------
initial
changed
changed
changed
