Obtaining Characters from Unicode Code Points in PHP

In PHP, handling Unicode characters requires specialized functions. Let's explore how to acquire characters corresponding to Unicode code points.

For instance, to obtain the character for U 010F:

<code class="php">var_dump(hexdec('010F')); // Output: 271
var_dump(mb_ord('ó')); // Output: 243
var_dump(mb_chr(243)); // Output: ó</code>

In this example, hexdec translates the hexadecimal Unicode code point to its decimal equivalent, making it suitable for use with Unicode-aware functions. mb_ord returns the code point of a given UTF-8 encoded character. Conversely, mb_chr generates a UTF-8 character from its code point.
