file_put_contents line breaks \n

[ggalan]

i am trying to put line breaks in a jSon txt file with line breaks but it doesnt seem to be responding. any suggestions please, thank you

$i = 0;
$entryText = '{"comments":[';
foreach($entryList['comments'] as $commentItem) {
	$num = $newStack[$i];
	
	$entryText .= "\n" . '{"index":'.$nTotal.',"text":"'.$arrTxt[$num].'","img":"'.$arrImg[$num].'"}';

	$i++;
	$nTotal--;
	if ($i < count($newStack)) {$entryText .= ','; }
}
$entryText .= ']}';

file_put_contents('data/cache.txt', $entryText);

sometimes i overlook the obvious, i had it encode a .txt instead of a .json file
