(PHP 5 CVS only)
iconv_substr -- Cut out part of a string
Description
string iconv_substr ( string str, int offset [, int length
[, string charset]])
Returns the portion of str specified by the start and length
parameters.
If start is non-negative, iconv_substr() cuts the portion
out of str beginning at start'th character, counting from
zero.
If start is negative, iconv_substr() cuts out the portion
beginning at the position, start characters away from the
end of str.
If length is given and is positive, the return value will
contain at most length characters of the portion that begins
at start (depending on the length of string). If str is
shorter than start characters long, FALSE will be returned.
If negative length is passed, iconv_substr() cuts the portion
out of str from the start'th character up to the character
that is length characters away from the end of the string.
In case start is also negative, the start position is calculated
beforehand according to the rule explained above.
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() always takes these for byte offsets. If charset
is not given, the character set is determined by the iconv.internal_charset
ini setting.
