Description:
------------
Intval documentation doesn't mention what the return value of intval applied to a non-nummeric string will be. Ie. Doesn't mention that

intval("this is not a number, and can never be interpreted as one"); 

will return -1.

Furthermore there's quite a few user contributed notes, that deal with intvals return value being undefined in case of integer overflow. This, IMHO, should be documented too.

Ooops, "will return -1" should read "will return 0"

These docs have been rewritten and will show up when the manual is next built. Thanks for the report! Here's the diff:
* http://cvs.php.net/diff.php/phpdoc/en/reference/var/functions/intval.xml?r1=1.3&r2=1.4

User notes and various return value information (including integer overflow) was added.
