This is my solution.
$s = preg_replace('/^\n+|^[\t\s]*\n+/m','',$s);
Bythos your code worked. the code from the "topic starter" did not in my case.
Thx. very useful.
plug and play perfect, worked like a charm.
@Bythos thanks! Your solution works for me, topic-starter - not.
Very useful
But if you want to remove all duplicated blank lines but want to preserve legibility, just replace, in the RegExp, the first '+' with {2,} and add one more \n in replacement.
my code is here
it can take care of a folder including sub folders.

If you want each line in an array, with no empty lines, try:
$lines = explode("\n",$multi_line_string);
$lines = array_filter($lines);
Good luck y'all!

It make me resolve many problems.
So thank you, guys.
