Frequently, you need to strip off unwanted characters or entities from the start and end of a string. For example, form field submissions, such as custom fields, typically require you to clean them up before processing. When you pull data from the database, many times, you need to clean it up before you process and then render it out to the browser.
In this episode, you’ll experiment with and learn about
trim. You’ll pass character masks to it to see how you can control what is stripped off.
If you listen carefully, you can hear the 1s and 0s flowing in your computer.
