Introduction iconv functions Examples using iconv Example Code More Information Introduction The iconv API is used for converting strings between different character encodings, it exposes the libiconv functionality embedded within Iguana.
If you are already familiar with this you will probably want to skip to If negative length is passed, iconvsubstr() cuts the portion out of str from the offset'th character up to the character that is length characters away from the end of the string.
In case offset is also negative, the start position is calculated beforehand according to the rule explained above. So, the string PHPFUNCTION(iconv) transforms to and you have to call libiconv() function instead of iconv(). I had seen this on FreeBSD, but I In contrast to strpos(), the return value of iconvstrpos() is the number of characters that appear before the needle, rather than the offset in bytes to the position where the needle has been found.
The characters are counted on the basis of the specified character set charset. In contrast to strlen(), iconvstrlen() counts the occurrences of characters in the given byte sequence str on the basis of the specified character set, the result of which is not necessarily identical to the length of the string in byte.
iconvstrlen Returns the character count of string iconvstrpos Finds position of first occurrence of a needle within a haystack iconvstrrpos Finds the last occurrence of a needle within a haystack Plain: Notice: iconv(): Detected an illegal character in input string in. \iconvexample. php on line 7 This is the Euro symbol ' iconvsubstr. obiconvhandler. iconv Functions.

If you need convert string from Windows1251 to 866. Some characters of 1251 haven't representation on DOS 866. For example, long dash chr(150) will be converted to 0, after that iconv finish his work and other charactes will be skiped.
