- Quick Tip: How to Trim Whitespace with PHP
- This article will discuss several methods and application scenarios for removing the beginning and end spaces of strings in PHP. Spaces in a string usually refer to spaces at the beginning or end. (The spaces between words are also spaces, but this article mainly focuses on the beginning and end spaces.) In PHP string processing, the beginning and the end spaces often cause trouble. Removing spaces can effectively clean and standardize data. The importance of removing spaces Give an example of the importance of removing spaces: Suppose that a user name is stored in the database, and a user accidentally adds a space at the end of the user name. This can cause problems with search or sorting. Use the trim() function to remove the beginning and end spaces to ensure that all usernames in the database are consistent in format and are easier to handle. Remove empty space when processing text-based data formats such as XML or JSON
