Array in PHP represents a map which assigns values to keys and can be treated as collection, queue, list (vector), stack, hash table, dictionary and others. Array values are not limited to a particular array and can be used as trees and multidimensional arrays. Sorting of arrays is a lengthy process and often time consuming. PHP functions we are about to mention help PHP developer in India sort them easily for any PHP development in India project. These functions easily allow a PHP developer to forge arrangement of elements inside an array and rearrange them in numerous distinct ways.

1) Simple sorting : The most basic and simplest array sorting function commonly used in any PHP development in India project is simple sorting. Using this a PHP developer in India can sort the array from lowest values to highest values and even numerically or alphabetically and is represented as sort(). Re-sort the arrays by using rsort(), it will robotically rearrange the values.

2) Using a Key to Sort : Using keys is an easy option to re-sort associative arrays again from highest to lowest. Dedicated PHP function for this is ksort() ...
... and it maintains key-value correlation during the process of sorting. A PHP developer in India can reverse sort by key using the ksort() function.

3) Sorting by value : If a project for PHP development in India needs that the array should be sorted using value instead of key then a PHP developer in India can use the sorting by value function using assort() instead of Ksort(). The same can be reversed using arsort().

4) Natural-language sorting : A wonderful function which can help sort functions in the PHP development in India project as if a human would do is the natural language sorting. The function uses human logic and not computational rules while sorting arrays. It is aptly called natural language sorting. PHP developers in India can use the function for their benefit while developing applications requiring higher level of logic.

5) Sorting by user-defined rules : Want to sort arrays so that they suit your user requirements, you can also do this using PHP with the sorting by user-defined rules. PHP developer in India can do this by defining own sorting algorithm which can be done by creating own comparison function and passing the same to usort(). Only thing to be careful about is to ensure that the function returns a number less than 0 if first argument is to be considered less than the second and vis a versa.

For example a PHP developer in India can create comparison using strlen() function to compare the number of characters in each string and then return a value which can be less or more in value as defined by the sorting.

6) Multidimensional sorting : For working on complex projects for PHP development in India which requires a comparatively complex sorting a PHP developer in India can use multidimensional sorting. The function is represented using array_multisort() and is hugely admired to be the most powerful. It can be used for various things.

eTatvasoft is an acclaimed PHP development in India company which aptly uses various sorting functions available in PHP to assign key values in all its projects.
