How can file_get_contents() and str_replace() be used to delete a specific line from a text file in PHP?

To delete a specific line from a text file in PHP, you can use file_get_contents() to read the contents of the file into a string, then use str_replace() to remove the specific line from the string. Finally, you can write the modified string back to the file using file_put_contents(). 

<?php
// File path
$file = 'example.txt';

// Read the file contents into a string
$content = file_get_contents($file);

// Line to delete
$lineToDelete = "This is the line to delete";

// Remove the specific line from the string
$content = str_replace($lineToDelete, '', $content);

// Write the modified string back to the file
file_put_contents($file, $content);
?>
