iconv(string $from_encoding, string $to_encoding, string $string): string|false

Converts string from from_encoding to to_encoding.

Параметри

from_encoding

The current encoding used to interpret string.

to_encoding

The desired encoding of the result.

If the string //TRANSLIT is appended to to_encoding, then transliteration is activated. This means that when a character can't be represented in the target charset, it may be approximated through one or several similarly looking characters. If the string //IGNORE is appended, characters that cannot be represented in the target charset are silently discarded. Otherwise, E_NOTICE is generated and the function will return false.

Застереження

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 to_encoding.

string

The string to be converted.

Значення, що повертаються

Returns the converted string, або false в разі помилки.

Зауваження:
The character encodings and options available depend on the installed implementation of iconv. If the argument to from_encoding or to_encoding is not supported on the current system, false will be returned.
