Yes, and trim() has sorted it out. Thank you for your help

[php array-search returns a blank]

Thank you for your response.  Yes var_dump does reveal a difference.

print_r(var_dump($text[2])) produces:   string(8) "charlie with the second " on a new line

print_r(var_dump($word)) produces:   string(7) "charlie"  

 

[php array-search returns a blank]

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 ?>
