PHP array, what to do with

PHP arrays
Array
(
[0] = pid=2
[1] = Action=save
[2] = 9=a
[3] = 10=a
[4] = 14=a
[5] = 20=a
[6] = 15=a
[7] = 15=b
[8] = 21=a
[9] = 21=b
[Ten] = 16=c
[One] = 16=d
[[] = 19=c
[+] = 19=d
[+] = 17=we
[[] = 22=keywork
[+] = 18=you
[+] = 23=thanks
)

Above the array, how to turn it to look like this:

Array
(
[0] = pid=2
[1] = Action=save
[2] = 9=a
[3] = 10=a
[4] = 14=a
[5] = 20=a
[6] = 15=ab
[7] = 21=ab
[8] = 16=CD
[9] = 19=CD
[Ten] = 17=we
[One] = 22=keywork
[[] = 18=you
[+] = 23=thanks
)
