iconv — Convert string to requested character encoding
iconv ( string $from_encoding , string $to_encoding , string $string ) : string|false
Performs a character set conversion on the string
The input charset.
The output charset.
If you append the string
to_encoding transliteration is activated. This means that when a character can't be represented in the target charset, it can be approximated through one or several similarly looking characters. If you append the string
//IGNORE, characters that cannot be represented in the target charset are silently discarded. Otherwise,
E_NOTICE is generated and the function will return
If and how
//TRANSLIT works exactly depends on the system's iconv() implementation (cf.
ICONV_IMPL). Some implementations are known to ignore
//TRANSLIT, so the conversion is likely to fail for characters which are illegal for the
The string to be converted.
Returns the converted string or
false on failure.
Example #1 iconv() example
<?php $text = "This is the Euro symbol '€'."; echo 'Original : ', $text, PHP_EOL; echo 'TRANSLIT : ', iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text), PHP_EOL; echo 'IGNORE : ', iconv("UTF-8", "ISO-8859-1//IGNORE", $text), PHP_EOL; echo 'Plain : ', iconv("UTF-8", "ISO-8859-1", $text), PHP_EOL; ?>
The above example will output something similar to:
Original : This is the Euro symbol '€'. TRANSLIT : This is the Euro symbol 'EUR'. IGNORE : This is the Euro symbol ''. Plain : Notice: iconv(): Detected an illegal character in input string in .\iconv-example.php on line 7
