I would like to find the value in an array using the key.
Like this:
$array=('us'=>'United', 'ca'=>'canada'); $key='ca'; How can I have the value 'canada'?

You can use the get() method of the dictionary ( dict ) to get any default value without an error if the key does not exist. Specify the key as the first argument. The corresponding value is returned if the key exists, and None is returned if the key does not exist.
The array_keys() function is used to get all the keys or a subset of the keys of an array. Note: If the optional search_key_value is specified, then only the keys for that value are returned. Otherwise, all the keys from the array are returned.
A dictionary is sometimes called an associative array because it associates a key with an item. The keys behave in a way similar to indices in an array, except that array indices are numeric and keys are arbitrary strings. Each key in a single Dictionary object must be unique.
It's as simple as this :
$array[$key]; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
