PHP Bug Type: Unknown/Other Function
Bug description: is_callable and __autoload
Description:
------------
When using is_callable on non-existing static class functions __autoload
will be called twice with some encoded (and thus non-existent) classname.
Reproduce code:
---------------
autoload.php
<?php
class test{
function notest(){
}
}
function __autoload( $classname ){
echo "let's require $classname!<br/>\n";
}
if( is_callable( array( 'test', 'test' ) ) ){
echo "test::test exists.";
}else{
echo "test::test doesn't exist.";
}
?>
Expected result:
----------------
test::test doesn't exist.
(no __autoload execution at all)
Actual result:
--------------
let's require 9akf!
let's require 9akf!
test::test doesn't exist.
