What are some best practices for searching for PHP functions or solutions online?

When searching for PHP functions or solutions online, it's essential to be specific in your search query. Include keywords related to the problem you are trying to solve, such as the error message or a description of the desired functionality. Look for answers on reputable websites, such as the official PHP documentation, Stack Overflow, or tutorial sites. Additionally, consider the date of the information you find, as PHP evolves over time, and older solutions may no longer be relevant.

if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
