I must to do this

$string="tested-x 4, mc dnd's 4, passenger 2, arrived 2, a.jhjhj.rts
4, te_ry4e_ll 4, pas44nger 2";

1st steps
$arr=explode(', ', $string);

and have
1---
Array ( [0] => tested-x 4
[1] => mc dnd's 4
[2] => passenger 2
[3] => arrived 2
[4] => a.jhjhj.rts 4
[5] => te_ry4e_12 4
[6] => pas44nger 2 )

now I must remove all elements where last two words aren't space4
[0] => tested-x 4 ok remain in the array
[3] => arrived 2 remove from array

and have this
2---
Array ( [0] => tested-x 4
[1] => mc dnd's 4

[4] => a.jhjhj.rts 4
[5] => te_ry4e_12 4
)

other step is remove space4 for to have this array
3---
Array ( [0] => tested-x
[1] => mc dnd's
[2] => a.jhjhj.rts
[3] => te_ry4e_12
)
