Status: Open
Bug Type: Arrays related
Operating System: RH 7.1
PHP Version: 4.0CVS-2002-03-1
New Comment:
Your second example isn't like the first. $a[0] is a reference to
itself. The first bonks because $GLOBALS['GLOBALS'] is a reference to
$GLOBALS. An equivalent is:
<?php
$a=array(1,2,3);
$a[3]=&$a;
array_merge_recursive($a,$a);
var_dump($a);
?>
which will produce the same results. I'm submitting a feature request
for array_recurse_safe($array) which returns an array with no infinite
loops.

I have talked to Zeev about this issues. Asked them may I have to fill
bug report and he said:
"They should either use hash_apply(), which automatically protects
against
recursion, or implement the recursion protection themselves (like
print_r()
does). You can/should open bug reports about them..."
In the start Zeev talks about some functions that have problems with
$GLOBALS and arrays that holds elements pointing ot itself.

I'm sure you can come up with a load of nasty things you can do with
$GLOBALS, but what do you want us to do about it? Disable $GLOBALS for
use with array_* functions (it that's even possible)? Disable $GLOBALS
at all?

<?php
array_merge_recursively($GLOBALS,$GLOBALS)
?>
On the test server all consoles hanged. 100%.CPU load. 98%
system - kswapd started to swap as a beast.
No problems with this.
<?php
$a=array(1);
$a[0]=&$a[0];
array_merge_recursive($a,$a);
var_dump($a);
?>
