Pimping Xdebug stack traces
I've always been annoyed by the way how Xdebug's stack traces looked liked. So I spend some time on making them look better. I will show the differences according to the following script:
<?php
ini_set('xdebug.show_local_vars', 'on');
ini_set('xdebug.dump_globals', 'on');
ini_set('xdebug.dump.GET', '*');
ini_set('xdebug.collect_params', 'on');
ini_set('xdebug.var_display_max_depth', 2);
function foo( $a )
{
for ($i = 1; $i < $a['foo']; $i++)
{
}
}
set_time_limit(1);
$c = new stdClass;
$c->bar = 100;
$c->foo = "12";
$a = array(
42 => false,
'foo' => 912125235,
0 => null,
3.141592654,
"testing",
array(),
$c, new stdClass,
fopen( '/etc/passwd', 'r' )
);
foo( $a, 42, null, false, "testing",
$c, fopen( '/etc/passwd', 'r' ) );
?>

The code for this will make it into CVS soonish.

Nice work, will make it a lot more enjoyable to work with xdebug with the new UI :-)
that's much better!
Great, looks much better than a patch I was thinking to submit but I never finished ;)
