------Solution--------------------
A lot:, study.

I:5; and later, are standard serialized strings, not including line breaks, spaces and other characters, stitching together is not

Unserialize (substr (...));
------Solution--------------------
You're out of context.
Remove the starting i:5; And after you remove the carriage return line break, serialize the string for PHP

Print_r (Unserialize ($s));

PHP Code

Array ([2] = = Array ([DF] = 0 [da] = 1) [] = = Array ( [DF] = 1 [da] + 1) [+] = Array ([df] = 0 [D A] + 1) [+] = Array ([df] = 0 [da] + 2) [4] = Ar Ray ([DF] = 1 [da] = 1) [+] = Array ([df] =    1 [da] = 1) [+] = Array ([df] = 0 [da] + 2)            [1] = = Array ([DF] = 1 [da] = 2) [3] = = Array (  [DF] = 1 [da] + 2) [129] = = Array ([DF] + 1 [da] = = 1))
------Solution--------------------
Learned, not serialized a few times.

I also study!!
