Answer by Soul_man for php function file_get_contents and first line of UTF-8 encoded text

(Try doing) -- wrong solution. see below

if($array_test[0] === "1") echo "first line";

and there is one function file() for such cases:

$file = file_get_contents ('./test.txt');$file_array = explode("\n", $file);

I was WRONG!

var_dump gives us an answer:

string(2) "1"

there is new line character in the string.

try doing:

$word = trim($line,"\r\n ");
