What are the potential pitfalls of combining two PHP scripts that involve reading and manipulating text files?

One potential pitfall of combining two PHP scripts that involve reading and manipulating text files is that there may be conflicts in variable names, functions, or file handles used in both scripts. To avoid this issue, you can encapsulate each script in a separate function or class to prevent naming conflicts and ensure proper encapsulation of variables and functions.

<?php
// Script 1
function script1() {
    // Code for reading and manipulating text files
}

// Script 2
function script2() {
    // Code for reading and manipulating text files
}

// Call the functions
script1();
script2();
?>
