Let's look at an example with a PHP array that holds names of different guitar manufacturers. Sort() function sorts an array in an ascending order. To PHP sort array by value, you will need functions asort() and arsort() (for ascending and descending orders). To PHP sort array by key, you should use ksort() (for ascending order) or krsort() (for descending order).

There are four functions for associative arrays - you either array sort PHP by key or by value.

First, we have the sort() method used to array sort PHP code in an ascending order.

Let's look at the various PHP array sorting functions. It's possible to array sort PHP by key or by value, in numerical, alphabetical, descending and ascending orders.We can add elements to the end of an associative array by adding keys with values or by concatenating a new key-value to the array. Add Elements to the End of an Associative Array in PHP. Where it gets complicated is when you need to. We need to do it dynamically to add elements before a particular key of an associative array.

Some of the functions can only be used for associative arrays. PHP provides a range of functions for sorting data based on either the key or value of an associative array.

PHP offers multiple built-in functions for PHP array sorting.

The most likely use case for this function is to insert a new member into a specific position in the array. This could be replicated, but let's be honest it's not really valuable.Īlso note that in the real world, the length parameter is probably useless in an associative array. Here's a cool tip for working with associative arrays- Here's what I was trying to accomplish: I wanted to hit a DB, and load the results into an associative array, since I only had key/value pairs returned. Note that in the built in array_splice method, the $length and $replacement parameters are optional.

The "after" slice, after our key's index, plus the lengthįinally, all that remains is to merge the three elements together, in order, using array_merge.

The "before" slice, before our key's index.

There are two ways to create an associative array: age array(Peter>35, Ben. The syntax for an associative array is to put the index within. Associative arrays are arrays that use named keys that you assign to them. With the index in hand, we can now effectively slice up our associative array into 3 pieces supports associative arrays (also known as hash tables) in which the index value is a string.

You might want to return false or an error instead.) (This part is sort of a choose-your-own-adventure. If we don't find the index in the array, simply return the original input array. With the given string key, we can then search the keys of the associative array for the index corresponding to this key. I've modelled this helper function on the built in array_splice method, with the key difference being the second parameter which is now a string key rather than a numeric index.
