PHP utf8_encode() Function
The PHP utf8_encode() function encodes an ISO-8859-1 string to UTF-8.
Unicode is a universal standard, and has been developed to describe all possible characters of all languages and includes a lot of symbols with one unique number for each symbol/character. UTF-8 has been used to transfer the Unicode character from one computer to another. However, it is not always possible to transfer a Unicode character to another computer reliably.

Example: applying on elements of an array
Consider one more example where all elements of an array are encoded and decoded.
<?php $str = array("\x31", "\x32", "\x33", "\x34", "\x35", "\x36", "\x37", "\x38", "\x39", "\x40", "\x41", "\x42", "\x43", "\x44", "\x45"); //encoding all elements of the array foreach($str as $i) echo utf8_encode($i)." "; echo "\n"; //decoding all elements of the array foreach($str as $i) echo utf8_decode($i)." "; ?>
The output of the above code will be:
1 2 3 4 5 6 7 8 9 @ A B C D E 1 2 3 4 5 6 7 8 9 @ A B C D E
