There are times when provider changes server and doesnt put everything back as it was before. Mostly this concerns PHP error reporting settings.
Of course, in old days nobody took a good care of proper coding so often $array[key] was used instead of $array['key'] and this is just one of the smallest things around.
I promise to write later a basic guide for avoiding common PHP error stuff like inproper use of quotes, also inside regular expressions (shame on you TCPDF, have you ever thought of checking your code with notices turned on?
Anyway, i also met people who just try to solve “notices” and “warnings” just by putting error_reporting(‘E_NONE’) but – come on. Its just curing symptoms, not the disease. I always prefer to code with everything turned on, even “notices”.
So, what did i want to say – even if something happens and you notice that the code you wrote long ago start to throw “notices” and “warnings” that doesnt break the code, but nicely break the layout, AND you dont have time (will, money) to refactor the code, and you still dont want to wander around all those millions of PHP scirpts you proudly used to call “CMS”… then just suppress all PHP errors in apache (if you dont use apache, then, so long…) level by putting this into .htaccess file of your web root:
php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value error_reporting 1
I hope i dont have to explain “how” to put .htaccess file in your web root and that you just can’t create .htaccess file on windows Xp (dunno about W7 or vista, i am Mac guy).
The code abode will put one centralized rule on all php scripts. Unless you have written error_reporting (E_ALL ~ E_NOTICES) in every file. If so, good luck removing them.
By the way you can do reverse psychology – evaluate the code of your freelancer by turning errors on all at once:
php_flag display_startup_errors on 1
php_flag display_errors on
php_flag html_errors on
php_value error_reporting 30719
1 – this works on PHP 5.3.x for PHP 5.2.x use
6143 and for later – 2047
More about constants you can read on php.net about predefined constants. especially i would point attention to “depreciated” stuff since that might not work after next “server upgrade”.
Just as remindment – if you want to hide code in php script, then put this in the beginning of index.php or any other place where you want to localize message:
<?php
ini_set('display_errors', 0);
error_reporting('E_NONE');
?>
or vide versa – shorthand to turn on all errors:
<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
?>
Take care,
Edgars
P.S yeye, i know i’ve been quiet for past few months, but i am back soon and when i am back i tell about all kinds of fun stuff like PHPUnit, design patterns like factory and singleton, new fun stuff from HTML5, how to build nice gallery just by uploading files via ftp and what else… naming variables and other cool things i am getting in touch with every day.
