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:




<?php
  
// Use preg_split() function
$string = "123,456,78,000"
$str_arr = preg_split ("/\,/", $string); 
print_r($str_arr);
      
// use of explode
$string = "123,46,78,000";
$str_arr = explode (",", $string); 
print_r($str_arr);
?>
Output:
Array
(
    [0] => 123
    [1] => 456
    [2] => 78
    [3] => 000
)
Array
(
    [0] => 123
    [1] => 46
    [2] => 78
    [3] => 000
)
