Array is one of the most vital portion of every programming language. In our web scripting like php, javascripts - we can not think multiple data manipulation without array. Most of the programmer afraid(!) with array. I don't know why?? I think array is one of the most easiest matter in this world.  :-D

Today I am going to present 4 important array manipulated PHP scripts. Today i discuss about-

1. array_change_key_case function.

2. array_chunk function.

3. array_combine function.

4. array_count_values function.

With this scripts i show you codes and corresponding demos. I hope you enjoy my tutorials. so,lets start.

1. How to use array_change_key_case() function:

*  This functions takes 2paramerts as input.

* First parameter contains an array and second parameter contains a keyword.

* There are two keywords exists for this function. such as- CASE_UPPER and CASE_LOWER.

* This function convert array index in to lowercase/uppercase depending on keywords.

2. How to use array_chunk() function:

* This function takes an array as input and it has additional 2 parameters.

* First parameters is an array, second parameter is size fo chunk and third parameter is a Boolean value which is optional.

* If third parameter is true then its chucked array  by maintain its indexed value. Otherwise chucked array index always starts from zero(0).

3. How to use array_combine() function:

* This function takes 2 arrays as input.

* First array element considered as key and second array element considered as value.

*It's return an array.

* It shows an error if any element is empty or number of elements does not matched.

4. How to array_count_values() function:

* This function takes an array as input.

* It show the number of occurrence of a value in an array.

* It return an array.

- Write a live Example of array_count_values() function:

Demo & Source Code

Bonus 2 More Array Function:

- How to get size of an array?

We can easily count the size of array element by php. There have 2 awesome function in php for counting size of array. First one is sizeof() and another is count(). Both return integer value.

5. How to use sizeof() function:

* This function takes an array as input.

*  The absolute value of number. If the argument number is of type float, the return type is also float, otherwise it is integer (as float usually has a bigger value range than integer).

*  It return integer value.

6. How to use count() function:

* This function takes an array as input.

* the number of elements in var. If var is not an array or an object with implemented Countable interface, 1 will be returned. There is one exception, if var is null, 0 will be returned.

*count may return 0 for a variable that isn't set, but it may also return 0 for a variable that has been initialized with an empty array. Use isset to test if a variable is set.

* It return integer value.
