Question

keep the original string format after modified?

$source1= "03aaa\r\n
04bbb\r\n
05ccc\r\n
04eee\r\n
05fff\r\n
04ggg\r\n
05hhh\r\n
08eee\r\n"

Can be

$source2= "03aaa04bbb05ccc04eee05fff04ggg05hhh08eee"

I want to keep the original format(if there are linebreak keep it like origin) after I made modified(added 07) the $source .

if input is like source1 format:

ouput:

$source1= "03aaa\r\n
  04bbb\r\n
  05ccc\r\n
  04eee\r\n
  05fff\r\n
  07fff\r\n
  04ggg\r\n
  05hhh\r\n
  07hhh\r\n
  08eee\r\n"

if input is like source2 format:

$source2= "03aaa04bbb05ccc07fff04eee05fff07fff04ggg05hhh007fff8eee"

How Can I got the expected result and keep the format like the origin?

Anyone could help me please?
