Who is faster between post or pre incrementation?

What is the fastest way to increment between post or pre incrementation in PHP?

Speed Test

First script

$i = 5;
$i++;

Second script

$i = 5;
++$i;

First script: 0.00027011525630951 seconds.
Second script: 0.00026511552333832 seconds.

Analyze opcode

First script analyze

function name:  (null)
number of ops:  6
compiled vars:  !0 = $i
line     # *  op                           fetch          ext  return  operands
---------------------------------------------------------------------------------
   2     0  >   EXT_STMT
         1      ASSIGN                                                   !0, 5
   3     2      EXT_STMT
         3      POST_INC                                         ~1      !0
         4      FREE                                                     ~1
         5    > RETURN                                                   1
 
branch: #  0; line:     2-    3; sop:     0; eop:     5
path #1: 0,

Second script analyze

function name:  (null)
number of ops:  5
compiled vars:  !0 = $i
line     # *  op                           fetch          ext  return  operands
---------------------------------------------------------------------------------
   2     0  >   EXT_STMT
         1      ASSIGN                                                   !0, 5
   3     2      EXT_STMT
         3      PRE_INC                                                  !0
         4    > RETURN                                                   1
 
branch: #  0; line:     2-    3; sop:     0; eop:     4
path #1: 0,

Conclusion

Pre incrementation is faster.
