In the context of PHP scripts, what are the potential consequences of incorrectly using functions like stripslashes() and fwrite()?

Incorrectly using functions like stripslashes() can lead to unintended removal of backslashes in strings, potentially causing security vulnerabilities. Similarly, misusing fwrite() can result in data being written to files in an insecure manner, opening up the script to potential attacks like code injection. 

// Correctly using stripslashes() to remove backslashes from user input
$input = "This is a backslash: \ ";
$clean_input = stripslashes($input);

// Correctly using fwrite() to write data securely to a file
$file = fopen("data.txt", "w");
$data = "This is secure data to be written to the file.";
fwrite($file, $data);
fclose($file);
