What are some common mistakes or oversights when using fwrite() in PHP, as illustrated in the forum thread?

Common mistakes or oversights when using fwrite() in PHP include not checking if the file was successfully opened, not handling errors properly, and not closing the file after writing. To solve these issues, always check if the file was opened successfully, handle errors using appropriate error handling mechanisms, and close the file after writing to ensure data integrity. 

$file = fopen("example.txt", "w");
if ($file) {
    fwrite($file, "Hello, World!");
    fclose($file);
} else {
    echo "Error opening file.";
}
