Are there any built-in functions or libraries in PHP that can streamline the process of editing specific lines within a text file?

To streamline the process of editing specific lines within a text file in PHP, you can read the contents of the file, modify the specific lines as needed, and then write the updated contents back to the file. One approach is to read the file line by line, keep track of the line numbers, make the necessary edits, and then write the modified lines back to the file. 

$file = 'example.txt';
$lines = file($file);

// Edit specific lines (e.g. line 3 and line 5)
$lines[2] = "This is the new content for line 3\n";
$lines[4] = "This is the new content for line 5\n";

// Write the modified lines back to the file
file_put_contents($file, implode('', $lines));
