iconv_substr - Cut out part of a string

SYNOPSIS
string iconv_substr (string $str, int $offset, [int $length = iconv_strlen($str, $charset)], [string $charset = ini_get("iconv.inter- nal_encoding")]) DESCRIPTION
Cuts a portion of $str specified by the $offset and $length parameters. PARAMETERS
o $str - The original string. o $offset - If $offset is non-negative, iconv_substr(3) cuts the portion out of $str beginning at $offset'th character, counting from zero. If $offset is negative, iconv_substr(3) cuts out the portion beginning at the position, $offset characters away from the end of $str. o $length - If $length is given and is positive, the return value will contain at most $length characters of the portion that begins at $offset (depending on the length of $string). If negative $length is passed, iconv_substr(3) 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. o $charset - If $charset parameter is omitted, $string are assumed to be encoded in iconv.internal_encoding. Note that $offset and $length parameters are always deemed to represent offsets that are calculated on the basis of the character set determined by $charset, whilst the counterpart substr(3) always takes these for byte offsets. RETURN VALUES
Returns the portion of $str specified by the $offset and $length parameters. If $str is shorter than $offset characters long, FALSE will be returned. SEE ALSO
