Sample String : 'The quick brown fox jumps over the lazy dog'

Visual Presentation:

Sample Solution:

PHP Code:

<?php
$my_string = 'The quick brown fox jumps over the lazy dog';
// Define the original string.

echo implode(' ', array_slice(explode(' ', $my_string), 0, 5))."\n";
// Split the string into an array of words, take the first 5 elements, join them with a space, and output the result.
?>

Sample Output:

The quick brown fox jumps 

Explanation:

In the exercise above,

• explode(' ', $my_string): Splits the string '$my_string' into an array of words using space ' ' as the delimiter.
• array_slice(..., 0, 5): Retrieves the first 5 elements from the array obtained from the explode() function.
• implode(' ', ...): Joins the selected elements from the array into a string with space ' ' as the glue.
• Finally, it echoes out the modified string, which consists of the first 5 words of the original string separated by spaces.
