How can the misunderstanding of PHP functions like chmod and file_put_contents lead to errors in code implementation?

Misunderstanding PHP functions like chmod and file_put_contents can lead to errors in code implementation if not used correctly. For example, mistakenly using chmod to change file permissions without proper understanding can result in security vulnerabilities. Similarly, misuse of file_put_contents can overwrite existing files unintentionally. To avoid such errors, it is crucial to thoroughly understand the documentation of PHP functions and their parameters before using them in code. 

// Correct way to use chmod and file_put_contents in PHP
$file = 'example.txt';
$content = 'Hello, World!';

// Set file permissions before writing content
chmod($file, 0644);

// Write content to file
file_put_contents($file, $content);
