in_array problem.

[shachi]

Hello,

I am simply trying to see if a value exists in an array of external file read by the file() function but unfortunately neither the in_array function is working nor the search_array. My code looks like this.

<?php
//$arr = array('red', 'green', 'blue');
$arr = file('colors.txt');
if(in_array('green',$arr)){
echo "Fount at index:".in_array('green',$arr);
} else {
echo "Not found";
}
?>

txt file, colors.txt

red
green
blue
green

It works with the arrays created with the array function but not with the file function any help would be appreciated. Thanks.

As stated in the manual, the array elements created by the file function including the new line characters that were present in the file. You haven't taken that into consideration.
