I want this code to work for me :) but i do not want to strip or change the file that is beeing fetched and saved in the local file.
Is it possible to change the stripAndSaveFile function to only save the content in the local file instaed of stripping and changing?

Another thing.. Is it possible to have the output xml decoded to json and saving it locally? so you can have a callback function to grab the data?

Kind regards,
R

I have added one simple little function to the class:

function getData() {
return file_get_contents($this->filePath);
}

$caching->getData() will then return the contents of the file.
I’m working with json data so wanted the raw text.
For people working with XML, they may want to change the line to:
simplexml_load_file($this->filePath);
as per the post above.

Thanks again for a great tutorial!

$data = simplexml_load_file($filepath);

Putting this in, instead of asking for $caching->getExternalInfo() greatly sped up my script ;)

It was probably just me, but I’m hoping that this comment will help others.

Thank you!

This is used to create a drop down from an external service to get all the states->cities they offer a service in. The crappy part, and the reason I am looping over the ‘cities.xml’ api call, is that each set of cities within a state must be called as an individual file that pulls in the cities for the currently looping state based on that state’s ID…major resource suck as the cities API call has to be made over 51 times (1 for each state).

I have modified your code for the stripFileAndSave function to read:

function stripAndSaveFile($xml,$first,$second,$attr1,$attr2) {
					// put the artist in an array
					$createForEachParam = $xml->$first->$second;

					// build our own XML based on the information we require
					$output = new SimpleXMLElement("<$first></$first>");

					// create new xml file
					$insert = $output->addChild($second);
					$insert = $output->addChild("id",$second[$attr1]->id);
					$insert = $output->addChild("name",$second[$attr2]->name);

					file_put_contents($this->filePath, $output->asXML());

		}

This is more of a generic class but still targeted toward the APIs I am calling as they have parents and children with the children having attributes (id and name).

Is this class capable of caching different files? In my case, I’m looking at up to 52 files. I have it set to a 3 hour interval to ensure that if new states or cities have been added, the application pull the correct list.

It is late and implementing caching to speed up my class and api calls is my next big goal. Gotta do more research first I think. Thanks again for writing this tutorial.

Cheers,
