You should quote your array keys: As is, it was looking for constants called department, name, email, message, etc. When it doesn’t find such a constant, PHP (bizarrely) interprets it as a string (‘department’, etc). Obviously, this can easily break if you do defined such a constant later (though it’s bad style to have lower-case … Read more
Just run php –ini and look for Loaded Configuration File in the output for the location of php.ini used by your CLI.
It’s the “null coalescing operator”, added in php 7.0. The definition of how it works is: It returns its first operand if it exists and is not NULL; otherwise it returns its second operand. So it’s actually just isset() in a handy operator. Those two are equivalent1: Documentation: http://php.net/manual/en/language.operators.comparison.php#language.operators.comparison.coalesce In the list of new PHP7 features: http://php.net/manual/en/migration70.new-features.php#migration70.new-features.null-coalesce-op And original … Read more
a short one: results in keys and values are swapped – you could fix that with array_flip() before the array_walk. array_walk_recursive requires PHP 5. you could use array_walk instead, but you won’t get ‘stack’ => ‘overflow’ in the xml then.
Intro First off you have a string. JSON is not an array, an object, or a data structure. JSON is a text-based serialization format – so a fancy string, but still just a string. Decode it in PHP by using json_decode(). Therein you might find: scalars: strings, ints, floats, and bools nulls (a special type … Read more
There are require and include_once as well. So your question should be… When should I use require vs. include? When should I use require_once vs. require The answer to 1 is described here. The require() function is identical to include(), except that it handles errors differently. If an error occurs, the include() function generates a warning, but the script will continue execution. The require() generates a … Read more
I’d use the try/catch block when the normal path through the code should proceed without error unless there are truly some exceptional conditions — like the server being down, your credentials being expired or incorrect. I wouldn’t necessarily use it to handle non-exceptional errors — say like the current user not being in the correct … Read more

If the WAMP icon is Orange then one of the services has not started. In your case it looks like MySQL has not started as you are getting the message that indicates there is no server running and therefore listening for requests. Look at the mysql log and if that tells you nothing look at the Windows … Read more
