What are the common causes of Strict Standards warnings in PHP code?

Strict Standards warnings in PHP code commonly occur when the code does not adhere to strict standards set by PHP. This can include issues such as using deprecated functions or not declaring variables before use. To solve this, you can update your code to follow the strict standards or adjust the error reporting settings in your PHP configuration.

// Adjust error reporting settings to hide Strict Standards warnings
error_reporting(E_ALL & ~E_STRICT);
