Description:
------------
I have a text with placeholders for images: ##-1 -> img No 1 ##-2 img No 2 etc.

It works fine with the reproduce code as long as the number is a single digit:

with numbers higher then 9 the image will be shown followed by the last digit.

Is it a bug?

Reproduce code:
---------------
$text "abc def ##-23 yxz";

$pic = "<img src = 'img-23'>";

$text_new = str_replace(*##-'.$pic, $image, $text);


Expected result:
----------------
(image shown)

Actual result:
--------------
(image shown)3
