![]() Actually array with updated values for is expected to be returned. NOTE: For the particular application I'm using, the ordering of the values when returned does not matter. You could, however, have unique keys each of whose corresponding values are arrays, and those arrays have multiple elements for each key. My problem is I'm getting the same array without changing the value of for all the array elements. Something like this involves arrays, keys, and values, so searching for that type of stuff tends to constantly point me to arraykeys() or arrayvalues(), neither of which is what I want. No, you cannot have multiple of the same key in an associative array. For that I written the following code in a function which returns the whole array: foreach($data as $value) => 8e9050a3646c98342b9ba079fba80982Īnd I want to convert the value of key into user readable format (i.e. While array_column() works for my scenario (if I were using PHP 5.5+ instead of PHP 5.3), it wouldn't work for the modified solution above (Hence the edit).I've a following associative array named $data Array The following solution worked in this scenario: $result = array_map(function($v), $people) If a later version of PHP adds this functionality, please state that in your answer. Something like this involves arrays, keys, and values, so searching for that type of stuff tends to constantly point me to array_keys() or array_values(), neither of which is what I want.įor the particular application I'm using, the ordering of the values when returned does not matter.Īlso, the version of PHP I'm using is 5.3. I've tried searching around for this, but I might not be using the right keywords. Yes, I know, I'm only saving myself 10 to 20 lines of code by not writing the function I need, but in a framework that uses tons of files, having to constantly include a library to do something this simple tends to get a little tedious. Given that PHP is littered with a plethora of quirky functions that do weird things, I'm wondering if something like this already exists. However, I doubt that I'm the first person to need this kind of functionality. I just need to do: $names = array_keyed_values($people, 'name') Get Specific Key/Value From Associative Array and Store. * array The Array of Keyed Values within the Array of Arrays.įunction array_keyed_values($array, $key)Ĭool, I've officially solved my problem. Get key and value from associative array and assign variable. 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. You can use the PHP arraykeys() function to get all the keys out of an associative array. Get the nth value from the list of values. Answer: Use the PHP arraykeys() function. To return the keys for all matching values, use arraykeys() with the optional searchvalue parameter instead. * string $key The Key within each Associative Array to retrieve the Value Get the value using the nth key from the data array. This is how associative arrays work in php, if you specify the key as you did, you don't get a numeric key. * array $array The Array of Associative Arrays. Your associative array here has string keys. it counts all the elements in an array (or object).But your assumption about the array containing four elements is wrong: '1' is equal to 1, so 1 > 'B' will overwrite '1' > 'A'. ![]() ![]() * Returns an Array of Values paired with the specified $key count works exactly as you would expect, e.g. Finally, you can use arrayvalues() to get all the values of the array, then take the first. I know that I could do this: $names = array() īut let's say that I'm lazy, so I create a function for it instead: /** Let's say that I have an array like this: $people = array(Īnd I want to know the names of all of these people.
