PHP 7.1 introduce a new check during conversion of string to number.
Example :
$ module load php70
$ php -v
PHP 7.0.8RC1 (cli) (built: Jun 8 2016 06:25:44) ( NTS )
$ php -r 'var_dump("1K" * 1024);'
int(1024)
$ module load php71
$ php -v
PHP 7.1.0alpha1 (cli) (built: Jun 8 2016 09:36:05) ( NTS )
$ php -r 'var_dump("1K" * 1024);'
PHP Notice: A non well formed numeric value encountered in Command line code on line 1
int(1024)
See it on 3v4l.org.
It is obvious that this new message is useful, but such code is very common.
Some examples in real projects:
You can start checking your code ;)
