Topic: Warnings After Updating to 7.1 PHP

[Bunty]

Pardon me, if I missed the fixes, but I get several warnings in error file after upgrading to 7.1 php, such as the following:

PHP Warning:  A non-numeric value encountered in /home/public_html/stormreports.php on line 602 
PHP Warning:  A non-numeric value encountered in /home/public_html/firedangerWD.php on line 69
PHP Warning:  A non-numeric value encountered in /home/public_html/atom-advisory.php on line 1065

Is there a way to fix these things?    Doesn't seem very important, since they don't seem to be hurting script operation from what I can tell.

In a problem I was having with a different php file, an easy generic fix was done by adding this in php.ini:  allow_url_fopen=1

For the atom-advisory.php, change the line above 1065 from

Code: [Select]

  $total_time = '';
to

Code: [Select]

  $total_time = 0.0;The stormreports.php script seems to be an older Curly script and likely has the same type issue (a numeric variable initialized to a blank string).
The firedangerWD.php likely has the same type issue.

Strong variable typing began enforcement with PHP 7 -- prior PHP versions were fast-and-loose with variable typing and automatically converted depending on the usage.  Now numeric, string and array have to be initialized to the respective 0.0, '', array() values first.

There were so many other errors and warnings in other php files, with some not functioning, for instance the AQI index, that I found it easier to change back to 5.6 php, in order to return the function of everything back to normal.   I would suggest people using 7+ php to check the function of their php scripts.

That's where keeping the scripts on the site up-to-date at current levels is a big reducer of angst when major PHP versions come along.

Not all scripts have the original author still maintaining their script base, but many still do, so it's a good idea to check their download site for updates before upgrading PHP versions.

All my scripts are tested with PHP 7+ and are backward compatible to 5.6 (at current script version levels).
