Write a PHP script to split the following string.

Sample string : '082307'

Visual Presentation:

Sample Solution:

PHP Code:

<?php
// Original string
$str1= '082307'; 
// Chunk the string into parts of 2 characters each and insert ':' between them
echo substr(chunk_split($str1, 2, ':'), 0, -1)."\n";
?>

Output:

08:23:07

Explanation:

In the exercise above,

$str1= '082307';: Assigns the string '082307' to the variable '$str1'.
chunk_split($str1, 2, ':'): Splits the string into chunks of 2 characters each and inserts a ':' between each chunk.
substr(..., 0, -1): Removes the last ':' from the resulting string.
