part1.*.part2 = 1

PHP file:
<?php
parse_ini_file('test.ini');

Why should it like it? That looks like a bug that got fixed by the 
new parser.

More like undocumented feature then. Nothing at http://www.php.net/parse_ini_file says that * cannot be used inside keys. So we are using it in a few in-house applications and this came as unpleasant surprise.

We can of course implement a different solution, if you really consider the current (5.2) behaviour bug.

In which case it would be nice to have a better explanation in parse_ini_file documentation with regard to what is considered a valid syntax and what not.

Jani, this wasn't broken by any of the re2c stuff.

The changes you made to zend_ini_scanner.l revision 1.48 are the cause.

I don't know how to allow literal * in re2c. (\* did not work)
And I don't have spare time to debug this. Ask Pierre if he has.

jani: try [*] or "*" to match a single '*' char
