Question

i have a very simple script that reads out a txt file, puts the content in an array.

Which does perfectly, i can do print_r($array); and it outputs all the data.

My script:

<?php

$file = 'countries.txt';
$countries_output = file_get_contents($file);

$countries_pieces = explode("\n", $countries_output);

if (in_array("Sweden", $countries_pieces)) {
   echo "Sweden was found";
}
else 
{
echo'NOT FOUND';
}
print_r($countries_pieces);
?>

I don’t understand why it doesn’t find the value ‘Sweden’ in my array, when it clearly is in there.

This is the output: https://pastebin.com/z9rC9Qvk

I also print_r the array, so you can see that ‘Sweden’ is indeed in the array.

Hope someone can help 🙂

Answer 1

Is countries.txt from a Windows machine? If so, splitting on ‘\n’ won’t work very well since there’s also a ‘\r’ for every line.

Your print_r output would seem to indicate that since there seems to be an extra newline between every line of output.
