There are more examples in the Usage part of the package's README. string(30) "alpha:bravo:charlie:delta:echo" Var_dump(TestStringBackedEnum::valueList(separator: ':')) string(34) "alpha, bravo, charlie, delta, echo" i am trying to get all array values of an multidimentional array, but the thing is array can be 1 levels deep or 2, 3 or 4, i.e. Var_dump(TestStringBackedEnum::valueList()) and the following for Backed Enum's, the following being a string example: string(30) "Alpha:Bravo:Charlie:Delta:Echo" Var_dump(TestEnum::valueList(separator: ':')) string(34) "Alpha, Bravo, Charlie, Delta, Echo" Results in the following being printed: In which produces the following for normal Enum's: Its a trait that can be easily added to any enum that does the following:Īdds a new static UnitEnum::valueArray(): array method that returns all values within an Enum as an equally typed array of Enum valuesĪdds a new static UnitEnum::valueList(string $separator = ', '): string method that returns all values within an Enum as a comma separated list string This example is an associative array, you can create numeric array in the same fashion.I've written a Composer package for this, othyn/php-enum-enhancements, as the UnitEnum::cases() method wasn't what I was looking for, as that returns an array of MySuperCoolEnum instances instead of the underlying values as their raw type, which is what I wanted. to many it might look like a) works, but actually b) is happening, when you needed c) all along. In this example we create a two dimensional array to store marks of three students in three subjects − you need a & - the other way (accepted) is sort of a subtle 'hack' - i.e the accepted answer by Rikesh works indirectly for reasons that are not obvious, i.e. Values in the multi-dimensional array are accessed using multiple index. And each element in the sub-array can be an array, and so on. "" Ī multi-dimensional array each element in the main array can also be an array. NOTE − Don't keep associative array inside double quote while printing otherwise it would not return any value. But, on the other hand, keys are normally smaller and the data could be hugely nested, so, on balance, using the arraykeys() is probably safer. Get the nth value from the list of values. Instead, we could use the employees names as the keys in our associative array, and the value would be their respective salary. Get the value using the nth key from the data array. To store the salaries of employees in an array, a numerically indexed array would not be the best choice. Let's assume I have the following multidimensional array (retrieved from MySQL or a service): array( array( id > xxx, name > blah ), array( id. Associative array will have their index as string so that you can establish a strong association between key and values. The associative arrays are very similar to numeric arrays in term of functionality but they are different in terms of their index. This function is explained in function reference. Here we have used array() function to create array. Exampleįollowing is the example showing how to create and access numeric arrays. These arrays can store numbers, strings and any object but their index will be represented by numbers. NOTE − Built-in array functions is given in function reference PHP Array Functions Numeric Array Multidimensional array − An array containing one or more arrays and values are accessed using multiple indices This stores element values in association with key values rather than in a strict linear index order. Values are stored and accessed in linear fashion.Īssociative array − An array with strings as index. Numeric array − An array with a numeric index. There are three different kind of arrays and each array value is accessed using an ID c which is called array index. For example if you want to store 100 numbers then instead of defining 100 variables its easy to define an array of 100 length. An array is a data structure that stores one or more similar type of values in a single value.
