The utf8_encode() function is an inbuilt function in PHP which is used to encode an ISO-8859-1 string to UTF-8. Unicode 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. It is not always possible to transfer a Unicode character to another computer reliably.
Syntax:
string utf8_encode( string $string )
Parameters: This function accepts single parameter $string which is required. It specifies the ISO-8859-1 string which need to be encoded.
Return Value: This function returns a string representing the encoded string on success or False on failure.
Note: This function is available for PHP 4.0.0 and newer version.
Example 1:
<?php // String to encode $string_to_encode = "\x63"; // Encoding string echo utf8_encode($string_to_encode); ?> |
Output:
c
Example 2:
<?php // Creating an array of 256 elements $text = array( "\x20", "\x21", "\x22", "\x23", "\x24", "\x25", "\x26", "\x27", "\x28", "\x29", "\x2a", "\x2b", "\x2c", "\x2d", "\x2e", "\x2f", "\x30", "\x31", "\x32", "\x33", "\x34", "\x35", "\x36", "\x37", ); // Encoding all characters foreach( $text as $index ) { echo utf8_encode($index) . " "; } ?> |
Output:
! " # $ % & ' ( ) * + , - . / 0 1 2 3 4 5 6 7
