In the following code: echo $text[2] returns the word at that index but echo $key returns a blank.

Can someone explain why is array-search not working in this  indexed array?

It does work when I test it with a key => value type array.

<?php $myfile = fopen("test.txt", "r") or die("Unable to open file!");

while(!feof($myfile)) {

  $text[] = fgets($myfile); }

fclose($myfile);

$word = $_POST['word'];

$key = array_search($word, $text);

echo $key ?>

The var_dump() output has now shown you why - the values are not the same. You search for "charlie" but array contains "charlie\n"

You could replace

$myfile = fopen("test.txt", "r") or die("Unable to open file!");

while(!feof($myfile)) {
    $text[] = fgets($myfile); 
}
fclose($myfile);
 

with

$text = file('test.txt', FILE_IGNORE_NEW_LINES);
