What are some common pitfalls to avoid when handling file operations and content manipulation in PHP scripts?

One common pitfall to avoid when handling file operations in PHP scripts is not properly checking for errors when opening, reading, writing, or closing files. It is important to always check for errors to ensure the operation was successful and handle any potential issues gracefully. 

$file = fopen("example.txt", "r");
if ($file === false) {
    die("Error opening file");
}

// Read file contents

fclose($file);
