caching a function's array result

[Confidence]

hi guys,

i have the following function

 

//getting all providers
function getAllProviders($tarifarray) {

$i = 0;
$provider_array = array ();
foreach ( $tarifarray ['tarifarray'] as $key => $val ) {
	$energyprovider = $val ['versorgerName'];
	$providerid = $i;
	$temparray = array ($energyprovider => $providerid );
	$provider_array = array_merge ( ( array ) $provider_array, ( array ) $temparray );
	$i ++;
}

return $provider_array;

}

 

and it is recalled in many cases with the same result....how can i configure it so it caches the return value? unless it changes.

you can store the result on global variable or something. You can't actually do what you want, cause in that case you need to check in the result is the same, witch is basically the same code. So you just have to store the result somewhere.

If the many calls you describe, are all on the same page, then you can set this up as a class, have the array as a class variable, then when instantiating you set up the array, then you would have a function to get the array when necessary.

 

The global storage is also an option as has been suggested.

 

If the resultant array is required on many pages, then storing it in the session would be an answer for you

thanks guys.

well if i have to check if it is same each time, then i am doing the calculation again which consumes resources...or not?

Yeah. Unless you put trigger or something on function that changes values, so it has to calculate only when someone changes values. I am not sure if that is possible in you case thought.
