Split a comma delimited string into an array in PHP

Given a long string separated with comma delimiter. The task is to split the given string with comma delimiter and store the result in an array.

Examples:

Input : geeks,for,geeks
Output : Array ( [0] => geeks [1] => for [2] => geeks )

Input : practice, code
Output : Array ( [0] => practice [1] => code )

Use explode() or preg_split() function to split the string in php with given delimiter.

PHP | explode() Function: The explode() function is an inbuilt function in PHP which is used to split a string in different strings. The explode() function splits a string based on a string delimiter, i.e. it splits the string wherever the delimiter character occurs. This functions returns an array containing the strings formed by splitting the original string.
Syntax:

array explode( separator, OriginalString, NoOfElements )

PHP | preg_split() Function: The preg_split() function operates exactly like split(), except that regular expressions are accepted as input parameters for pattern.

Syntax:

array preg_split( string $pattern, string 
$subject [, int $limit = -1 [, int $flags = 0 ]] )

Example:

Array
(
    [0] => 123
    [1] => 456
    [2] => 78
    [3] => 000
)
Array
(
    [0] => 123
    [1] => 46
    [2] => 78
    [3] => 000
)
