Summary: exception not catchable when thrown from autoload in
an extended class
Status: Not a bug
Type: Bug
Package: Scripting Engine problem
Operating System: Linux
PHP Version: 5.5.0

New Comment:
Nevermind, I see the issue now and why it's expected behavior. The autoload
gets called when the class is declared rather than when the class is first
called. I'll see if your fix in bug 65254 resolves the issue I was having.
Thanks again for your help.

Thank you for your help. Why does it matter if the class was declared
literally in the try/catch block? The documentation states "exceptions thrown
in the __autoload function can be caught in the catch block". It works for the
base class, but not extended classes.
Other exceptions thrown outside of a try/catch always propagate back to the
caller's try/catch such as the below. In these examples, the exception is
caught, but the exception is thrown outside of the literal try/catch.
<?php
function __autoload($class)
{
throw new Exception('abcd');
}
try
{
test1::go();
}
catch (Exception $e)
{
echo 'caught';
exit;
}
=================================================
<?php
function test()
{
throw new Exception('abcd');
}
try
{
test();
}
catch (Exception $e)
{
echo 'caught';
exit;
}
=================================================
<?php
class test1
{
public static function go()
{
throw new Exception('abcd');
}
}
try
{
test1::go();
}
catch (Exception $e)
{
echo 'caught';
exit;
}

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
try the following example, you may found why this is expected:
<?php
function __autoload($class)
{
throw new Exception('abcd');
}
try
{
class test1 extends test2
{
public static function go()
{
}
}
test1::go();
}
catch (Exception $e)
{
echo 'caught';
exit;
}

Description:
------------
This issue may be the same issue as bug 65254 that I just submitted. The
following script throws a Fatal Error rather than catching the exception.
Test script:
---------------
<?php
function __autoload($class)
{
throw new Exception('abcd');
}
class test1 extends test2
{
public static function go()
{
}
}
try
{
test1::go();
}
catch (Exception $e)
{
echo 'caught';
exit;
}
Expected result:
----------------
caught
Actual result:
--------------
Fatal error: Uncaught exception 'Exception' with message 'abcd' in
/tmp/test.php:4
Stack trace:
#0 /tmp/test.php(8): __autoload('test2')
#1 {main}
thrown in /tmp/test.php on line 4
