The explode function is used to split a string into an array. Its usage is as follows:

Split the string using the specified delimiter and optional limit.

Explanation of parameters:

  1. Delimiter: specifies the separator for the given string, which can be a single character or a string.
  2. String: The string to be split.
  3. Limit (optional): Specifies the maximum number of elements that can be included in the returned array.

Return value: returns an array containing the substrings obtained by splitting the string based on the specified delimiter.

I am currently studying for my exams.

I am currently preparing for my exams.

$str = "Hello,World,PHP";
$arr = explode(",", $str);
print_r($arr);

Output:

Array
(
    [0] => Hello
    [1] => World
    [2] => PHP
)

In the given example, the string “$str” is split by commas to create an array “$arr” with the elements being the substrings after the split.
