Why is textarea filled with mysterious white spaces?

There could be a number of reasons why a textarea element in a PHP webpage might be filled with mysterious white spaces. Some possible causes could include:

1. Extra white space or line breaks in the PHP code itself: Make sure that there are no extra white spaces or line breaks before or after the textarea element in your PHP code.

2. White space in the default value of the textarea: If you have set a default value for the textarea element, make sure that there are no extra white spaces in that value.

3. White space entered by the user: If the textarea is being populated with user-generated content, it's possible that the user has accidentally added extra white space to the content.

4. A problem with the website's design or stylesheet: If the problem is not related to the PHP code or the content of the textarea, it could be caused by a issue with the website's design or stylesheet. Make sure that there are no conflicting styles or layout issues that could be causing the problem.

To troubleshoot the issue, you may want to try inspecting the textarea element using your web browser's developer tools, and looking for any clues as to what might be causing the extra white space.
