Re: PHP number auto-converting doesn't work for negative #'s without a leading digit

Autoconversions in any language are not always perfect (in particular from string representations to numbers), that is why I tend to cast in my own code. In this case, it might be a question of tunning the Zend parser to recognize the abbreviated construct you show as a valid float, although strictly it should have the zero in front (it is just customary to sometimes omit it). Also, you might want to reclassify it as a Zend Engine or Scripting Engine bug, as the decision as to whether something looks like a float is done in places like: php-src/ZendEngine2/zend_operators.h:is_numeric_string() Cheers. --- Justin Patrin <papercrane@gmail.com> wrote: > Just thought you all might like to know: > http://bugs.php.net/bug.php?id=31889 > > This is a pretty simple bug which affects scripts which assume PHP > will convert a string to a number automatically.
