Original String : 'The quick brown fox'

Visual Presentation:

Sample Solution:

PHP Code:

<?php
$s = 'The quick brown fox';
// Define the original string.

// Split the string into an array using space as the delimiter after removing leading and trailing whitespace.

echo $arr1[0]."\n";
// Output the first element of the resulting array.
?>

Explanation:

The above PHP code snippet takes the string 'The quick brown fox', trims any leading or trailing whitespace, and then splits it into an array using the space ' ' as the delimiter. The explode() function splits a string into an array by breaking it into substrings based on a specified delimiter. Here, it creates an array $arr1 containing the words 'The', 'quick', 'brown', and 'fox'. Finally, it echoes out the first element of the resulting array, which is 'The'.
