PHP String Exercises: Remove part of a string

Sample Solution:

PHP Code:

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

echo str_replace("fox", " ", $my_str)."\n";
// Replace all occurrences of "fox" with a space in the original string and output the result.
?>

Output:

The quick brown   jumps over the lazy dog 

Explanation:

The above PHP code snippet takes the string 'The quick brown fox jumps over the lazy dog' and replaces all occurrences of the substring 'fox' with a space ' ' using the str_replace() function. The "str_replace()" function searches for a specific substring in a string and replaces all occurrences with another substring. Here, it replaces all occurrences of 'fox' with a space, resulting in the string 'The quick brown jumps over the lazy dog'. Finally, it echoes out the modified string.
