What are some recommended best practices for accurately measuring string width in PHP?
When measuring string width in PHP, it is important to consider the impact of multi-byte characters, as they can affect the accuracy of the measurement. To accurately measure string width, it is recommended to use the `mb_strlen()` function in PHP, which calculates the length of a string taking into account multi-byte characters. This ensures that the width of the string is measured correctly, especially when dealing with languages that use multi-byte characters.
$string = "Hello, 你好";
$width = mb_strlen($string, 'UTF-8');
echo "String width: " . $width;
