Parameters
string
The input string.
An array of strings can be provided, in which case the replacements will occur on each string in turn. In this case, the
replacement
, start
and length
parameters may be provided either as scalar values to be applied to each input string in turn, or as arrays, in which case the corresponding array element will be used for each input string. replacement
The replacement string.
start
If
start
is non-negative, the replacing will begin at the start
'th offset into string
. If
start
is negative, the replacing will begin at the start
'th character from the end of string
. length
If given and is positive, it represents the length of the portion of
string
which is to be replaced. If it is negative, it represents the number of characters from the end of string
at which to stop replacing. If it is not given, then it will default to strlen( string
); i.e. end the replacing at the end of string
. Of course, if length
is zero then this function will have the effect of inserting replacement
into string
at the given start
offset.
