The convert_cyr_string() function is used to convert a string from one Cyrillic character-set to another set. It was introduced in PHP3. The character sets to be converted are specified with a single character code. Look at the types that are supported by this function:
“k - koi8-r “w - windows-1251 “i - iso8859-5 “a - x-cp866 “d - x-cp866 “m - x-mac-cyrillic
If an invalid code is specified for the source and/or destination argument, the function generates a warning.
Note: The presence of a null byte (\0) in the string halts the translation at that point.
convert_cyr_string(string $str, string $from, string $to): string
|str||The string to be converted.|
|from||The source Cyrillic character set, as a single character.|
|to||The target Cyrillic character set, as a single character.|
