Subject: New String Function: str_replace_limit
From: dragoonis@gmail.com (Paul Dragoonis)

Hey,

I'm proposing to add a new function str_replace_limit, this will be
identical to str_replace() with one key difference, you can specify
how many times you want the replace to occur.

Currently this isn't possible with any functions in the
/ext/standard/string.c stack, the only easy workaround is using
preg_replace() which requires of course the pcre library and regex
patterns.

I would have added this as a 4th param to str_replace(), but it
already has a 4th by-ref param to tell you how many times it done the
replacement.

mixed str_replace_limit ( mixed $search , mixed $replace , mixed
$subject [, int $limit ] )

Thoughts?

Paul Dragoonis.
