Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Example:
    <?php
    echo substr_replace('abcde', 'f', array(0, 1), array(1, 1));
    ?>

Expected output:
    ffcde

Actual output: 
    Warning: substr_replace(): Functionality of 'from' and 'len' as
    arrays is not implemented in - on line 2
    abcde

I agree that it'd be very nice if one could pass a buffer as the input string, with arrays of offsets, lengths, and replacement strings (which is something I need to accomplish), but per the documentation, use of arrays for the replacement, offset, and lengths are only valid if the input string itself is passed as an array, and in that case, this function will return an array, not a string.

This is best categorized as a desired functionality, but it's not a bug.
