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: ':')) You can use the PHP arraykeys() function to get all the keys out of an associative array. string(34) "alpha, bravo, charlie, delta, echo" Answer: Use the PHP arraykeys() function. Var_dump(TestStringBackedEnum::valueList()) I have a multidimensionalarray and I'm trying to output all values with a certain key. Alternatively, you could also use arraymap(). So I've been trying to figure this out for a while now and seem to be stuck.
Php associative array get all values upgrade#
and the following for Backed Enum's, the following being a string example: If you're using a previous PHP version and can't upgrade at the moment, you can use the Userland implementation of arraycolumn() function written by the same author. string(30) "Alpha:Bravo:Charlie:Delta:Echo" For the sample data those inner calls to get the values in the reference column yield the same value - that could be stored in a variable before the loop and used in those two lines, which would eliminate the call on each iteration of the loop where the count of that value occurs more than once. 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 How can I get an array of values from an associative array Associate array Example: Array ( 0 > Array ( 0 > 1 1 > 2 2 > 3 ) 1 > Array ( 0 > 4 1 > 5 2 > 6 ) 2 > Array ( 0 > 7 ) ) Desired Output. So trying to differentiate between integers and numeric strings is unnecessary.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. Let's assume I have the following multidimensional array (retrieved from MySQL or a service): array( array( id > xxx, name > blah ), array( id. In other words, there is no such thing as an array key of "8" because it will always be (silently) converted to the integer 8. The indexed and associative array types are the same type in PHP, which can both contain integer and string indices. key with multiple values is also an array, So here is array inside array N is called multidimensional array. No, but you can have array with this multiple values as the value in first array, like array ('key1' > array ('value1', 'value2')). "8" will be interpreted as 8, while "08" will be interpreted as "08"). array key1 > value1, value2, value3 array key2 > value4, value5, value6. If a key is the standard representation of an integer, it will be interpreted as such (i.e. Assuming keys in the sub arrays are unique you can. You can use the PHP arrayvalues() function to get all the values of an associative array. From the array documentation:Ī key may be either an integer or a string. Answer: Use the PHP arrayvalues() function. There are three different kind of arrays and each array value is accessed using an ID c which is called array.
For example if you want to store 100 numbers then instead of defining 100 variables its easy to define an array of 100 length. Many commenters in this question don't understand how arrays work in PHP. An array is a data structure that stores one or more similar type of values in a single value.
