Edit report at https://bugs.php.net/bug.php?id=63406&edit=1 ID: 63406 Comment by: mail+php at requinix dot net Reported by: n at p12a dot org dot uk Summary: Count *does* detect infinite recursion Status: Open Type: Documentation Problem Package: Documentation problem PHP Version: master-Git-2012-10-31 (Git) Block user comment: N Private report: N New Comment: ...and the number may be wildly inaccurate. Sounds like a bug: counts first and stops recursion second? $a = array(1, 2, 3); $a[] =& $a; $a[] =& $a; $a[] =& $a; echo count($a, COUNT_RECURSIVE); // 78 Did you know you can easily submit changes to the online documentation? Look for the [edit] in the top-right corner of manual pages. I've submitted some changes for you: "count: detects recursion (bug #63406)" http://edit.php.net/?patchID=761&project=PHP Previous Comments: ------------------------------------------------------------------------ [2012-10-31 19:37:23] n at p12a dot org dot uk Description: ------------ --- From manual page: http://www.php.net/function.count#refsect1-function.count- parameters --- The manual says "count() does not detect infinite recursion". But count() does. Test script: --------------- $a = array(); $a[] = &$a; echo count($a, 1), "\n" Expected result: ---------------- Most probably an out-of-memory error, which is what I get when infinitely recursing in a user-defined function. Actual result: -------------- PHP Warning: count(): recursion detected in Command line code on line 1 3 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63406&edit=1
