$search = array(
'/required/',
'/min\=(\d+)/',
'/max\=(\d+)/',
'/\w+\=([^=]+)/',
);
$replace2 = array(

in this case, the result is still ="3" =code

"=" will be quoted to "\=", in this case, the result is R\=1 R\="3" R\="5" too,
whenever "\=" or "\\=".

This is not a bug. '=' has special meaning in ?= and ?<= expressions and it is
on
the list of characters quotes by preg_quote.

Description:
------------
$search = array('/required/','/min\=(\d+)/','/max\=(\d+)/','/\w+\=([^=]+)/',);
$replace2 = array('R=1','R="$1"','R="$1"',);
It seems doesn't work correctly when replacement contains "="
Test script:
---------------
$search = array('/required/','/min\=(\d+)/','/max\=(\d+)/','/\w+\=([^=]+)/',);
$replace1 = array('R1','R"$1"','R"$1"',);
$replace2 = array('R=1','R="$1"','R="$1"',);
$replace3 = array('R\\=1','R\\="$1"','R\\="$1"',);
$from = 'required min=3 max=5 code=code';
echo preg_replace($search, $replace1, $from);
echo preg_replace($search, $replace2, $from);
echo preg_replace($search, $replace3, $from);
Expected result:
----------------
R1 R"3" R"5"
R=1 R="3" R="5"
R\=1 R\="3" R\="5"
Actual result:
--------------
R1 R"3" R"5"
="3" =code
R\=1 R\="3" R\="5"
