PHP - Handling UTF-8 Filenames on Windows
Problem Statement
Uploading files with UTF-8 encoded filenames results in distorted characters on Windows.
Proposed Solution
The original proposal to solve this issue involved using the iconv() function to convert the filename to a code page that is compatible with the Windows system, such as CP1258. However, this approach has limitations.
Updated Solution
In reality, PHP filesystem functions can only handle characters that are within the system's active code page. Therefore, two possible solutions arise:
Option 1:
- Restrict filename characters to the system's code page (e.g., CP437 in your case)
- This option limits the use of Vietnamese characters.
Option 2:
- Change the system's code page to Vietnamese (e.g., CP1258)
- Convert the filename to the new code page (e.g., $fn2 = iconv("UTF-8","cp1258", $base_dir.$fn);)
- This option also limits filename characters to the Vietnamese code page 1258.
Disadvantages of Both Options:
- Option 1: Inability to use certain Vietnamese characters
- Option 2: Requirement to change system code page and limitations on filename characters
Additional Information on Changing System Code Page
To change the system's code page:
- Navigate to Control Panel > Region
- Select the "Administrative" tab
- Under "Language for non-Unicode programs," click the "Change system locale" button
- Select "Vietnamese(Vietnam)" from the drop-down menu

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
