[program-l] Weird/strange issue with PHP file

Ok, another, unrelated question/guess - have a main, index.php file that loads
another one in using the require() function, and that second file has a
class/object defined in it, with properties, functions, etc., including the
following function definition:
public function setPosition($sPlayer = "red", $iPosition = 3, $iPieceIndex = 0)
{
$iIndex = array_flip($this->arPlayers)[$sPlayer];
$this->arPositions[$iIndex][$iPieceIndex] = ($iPosition -1);
}//end of setPosition function
Anyway, issue was that whole main page was just sort of locking up/making
server/browser hang/lock up for roundabout 5 minutes, until browser would
generally say something like 500 error, but with no further details, and this
is something that was operating fine on my windows7 64 bit machine, running
under WAMP, but would do this when uploaded files to linux box for actual
hosting.
Anyway, sort of assumed it was again maybe something related to some or other
strange bit of character encoding in one of the file's contents, so firstly
told notepad++ to make sure both of the files had their character set encoding
set to UTF-8 without BOM, but no go, so then stripped both files down to
literally nothing and started putting the contents back in, piece by piece to
try track down what was causing issue.
Anyway, eventually had whole of index.php back again, until I again told it to
require() the second file, and then issue started again, so there, started off
again copying/pasting the second files's contents back in bit by bit, and got
down to the last function, and that was the one copied in here above - also
literally copied and pasted it into this message.
Either way, when it turned out that that re-caused the problem, I then firstly
tried stripping it's contents down line by line, and turned out was the first
line causing the issue:
$iIndex = array_flip($this->arPlayers)[$sPlayer];
So, then tried retyping it sort of manually in case there was in fact some or
other strange character in there wasn't seeing, but, nope, so then redid the
same operation from that line into the 2 following lines:
$arFlipped = array_flip($this->arPlayers);
$iIndex = $arFlipped[$sPlayer];
Then left the rest of it as before, and all fine/working now.
Makes me think/wonder that again it must/might have something to do with a sort
of hidden character like at line end, or something, but pretty sure made sure
cleaned up whole lines, etc. before trying to retype, etc., but, either way,
really not too sure what could thus cause it to sort of hang up as if I'd
initiated an eternal recursive array iteration, or something, unless it's
something to do with PHP versions, or something, but that doesn't really make
much sense if the same functionality now works split into 2 lines, instead of
just operating in one, or something...?
Thoughts, etc.?
Stay well
