Re-encoding Files to UTF-8
You have a collection of files that aren't in UTF-8 encoding, and you're in the process of converting your site to use UTF-8. To facilitate this transition, you've devised a simple script that reads in the files and saves them in UTF-8, but the resultant files retain their old encoding.
Here's the script in question:
To successfully save the files in UTF-8 encoding, you need to add the UTF-8 Byte Order Mark (BOM) to the beginning of each file:
With this addition, your script will effectively encode the output files in UTF-8, ensuring compatibility with modern web standards.
The above is the detailed content of Why Are My Re-Encoded Files Still Using Their Old Encoding?. For more information, please follow other related articles on the PHP Chinese website!

The best ways to send emails using PHP include: 1. Use PHP's mail() function to basic sending; 2. Use PHPMailer library to send more complex HTML mail; 3. Use transactional mail services such as SendGrid to improve reliability and analysis capabilities. With these methods, you can ensure that emails not only reach the inbox, but also attract recipients.

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.
