Visual Presentation:

Sample Solution:

PHP Code:

<?php
$original_string = 'The brown fox'; 
// Define the original string.
$string_to_insert ='quick'; 
// Define the string to be inserted.
$insert_pos = 4; 
// Define the position where the insertion will occur.
$new_string = substr_replace($original_string, $string_to_insert.' ', $insert_pos, 0); 
// Insert the substring at the specified position in the original string.
echo $new_string."\n"; 
// Output the modified string.
?>

Output:

The quick brown fox

Explanation:

The above PHP code snippet inserts the string ''quick'' into the original string ''The brown fox'' at position 4 (zero-based indexing). It uses the 'substr_replace()' function, which replaces a portion of a string with another string. The inserted string is followed by a space to ensure proper spacing. Finally, it outputs the modified string ''The quick brown fox''.
