my question is the following: How do I search a key and return its value?
Ex.
$contagem = array('metodologia' => '1','facilidade' => '10')
would like to search for ease and return the value 10.
Grateful!

You can use the name of the variable followed by the field you want to pick, for example.
$contagem['facilidade']

Actually this search I will do with a variable passed in the function. this stop I need to locate, it will not always be in the array. I did it with foreach and pregmatch but it became unviable, the array has a little more than 2k of record and stops it around 6k of record. I already needed to restart the apache service because of this.

I get the idea to search the key, if it is true it seeks the value in this way, it would be the best solution?

Just use
if isset($contagem[$strComNomeDoCampo]) == trueuse the value... -
You can use the function
array_key_existsorin_arrayto check if the key exists in the array.
