php文件大小有问题吗？

i have a file of php codes

does it matter if this files size is 50kb every script is uncompressed like this

a
b
c
  c1
    c1c
       c1c1

       c1c2

       c1c3
d
  d1
  d2
  d3
  d4

and it is 13kb if compressed like this

a
b
c c1 c1c c1c1 c1c2 c1c3
d d1 d2 d3 d4

if it is uncompressed it is readable and faster to edit but if compressed it is still easier to edit for me but sometimes i get lost in it

i want to know if it affects the speed of the script and the speed on the client side because i want it to be as fast as possible

and is it the same for php-html merges like

<tag value="<?php
     a
     b
     c
?>"></tag>

and

<tag value="<?php a b c ?>"></tag>
