The **`str_split()` function** splits the content of a string into an array. 

This function is similar to the `explode()` function, but whereas the `explode()` function converts whole words that make up the string into separate arrays, the `str_split()` function converts every character in the string into an array item unless told otherwise. 


#      
## Syntax
```
str_split($string, $length);
```
## Parameters
* `$string`: The first parameter will be a string whose content will be split into an array.
* `$length`: The second parameter is an optional integer that will determine the length of the split chunks if provided.

## Return value

* If the `$length` parameter, which is optional, is passed, the returned array will have chunks with lengths equal to the provided  `$length`. Otherwise, each item will be one character in `$length`.

* The return value will be `false` if the length passed is less than `1`. 

* If a `$length` value exceeds the string's length, the whole string is returned as the first and only item of the array. 

## Support
This function is available for use in PHP version 5 and later.

## Code
In the code snippet below, a string with the value `"Welcome Back"` is stored in `$myString` variable and passed to `str_split()`. 

In the first instance, we provide only a string parameter, while in the second instance, we also pass the `$length` parameter.



<?php
    $myString = "Welcome Back";

    print_r(str_split($myString));
    print_r(str_split($myString, 4));
?>


#      
## Syntax
```
str_split($string, $length);
```
## Parameters
* `＄string`: The first parameter will be a string whose content will be split into an array.
* `＄length`: The second parameter is an optional integer that will determine the length of the split chunks if provided.

## Return value

* If the `＄length` parameter, which is optional, is passed, the returned array will have chunks with lengths equal to the provided  `＄length`. Otherwise, each item will be one character in `＄length`.

* The return value will be `false` if the length passed is less than `1`. 

* If a `＄length` value exceeds the string's length, the whole string is returned as the first and only item of the array.
