Undefined errors since host PHP upgrade

It appears my host has done some upgrades to the latest PHP. Since this update some of my scripts are throwing errors. I am not sure why these errors are being generated as it looks ok to me. I can turn error reporting off and they go away but I would rather do it right and fix the error. The errors don't cause the script to not work, just throws the annoying error.  Maybe I just need another set of eyes and someone with a little more experience than I have as the variable looks to be defined unless I am missing something. 

 

Here is the page

 

http://www.mesquiteweather.net/wxspotter.php

 

Here is where it says the error starts

    $noStormMessage                                     .= "<table style='{$noMessageStyle}' cellpadding='0' cellspacing='0'>\n";
    $noStormMessage                                     .= "<tbody>\n";
    $noStormMessage                                     .= "  <tr><td style='{$td1Style}'>LIVE STORM SPOTTER REPORTS</td></tr>\n";
    $noStormMessage                                     .= "  <tr><td style='{$td4Style}'>There are currently no storm reports</td></tr>\n";
    $noStormMessage                                     .= "</tbody>\n";
    $noStormMessage                                     .= "</table>\n";
    $noStormMessage                                     .= $afterTable;

Here is the full script

Chances are these errors have always been there, but the update revealed them to you where they were hidden before. The first is because of this line:

 

 

$noStormMessage .= "<table style='{$noMessageStyle}' cellpadding='0' cellspacing='0'>\n";

 

That's saying "concatenate the right side of the = with the existing string in the $noStormMessage variable". Problem is, there *is* no existing variable called $noStormMessage. Solution to that is not to use .= in that line, but just =.

 

The other two are related and self-explanatory. You have no array variable defined called $stormTypesAry until *after* you're trying to use it. Move the definition of this variable before the attempt to use it.

This shouldn't have been hidden before since e_reporting was on. They didn't become errors until the update. 

 

$noStormMessage is defined that is the thing. If that is the problem then $tData would also be showing as undefined. changing .= to =. does nothing. 

 

$stormTypesAry is clearly defined before it is used if you look closely. 

 

I am not sure what you're trying to say.

Simply put, an array should exist before you try to access it

This shouldn't have been hidden before since e_reporting was on. They didn't become errors until the update. 

 

Note that there are multiple levels of error reporting. Perhaps the following will help:

http://www.php.net/manual/en/function.error-reporting.php

 

Also note that there's a setting which determines whether or not those errors are displayed to the screen:

http://www.php.net/manual/en/errorfunc.configuration.php#ini.display-errors

It looks like you defined $tData here:

//...
 
//Set initial output to false
$tData = false;
foreach($xml->report as $report)
 
//...
