array problems

i have a counter script on my page (courtesy of david harrison) but when i try to implement it i get the following message:

[QUOTE]

Warning: array_rand() [function.array-rand]: First argument has to be an array in …/plugins/randomheader.php on line 41

[/QUOTE]

any suggestions on what this might mean? line 41 ends up being one line in the array itself

[code=php]<?php
$count_file_path = “counter.txt”;

if( file_exists($count_file_path) ){

$count_file = fopen($count_file_path, “r”) or die(“”);
$curr_count = fgets($count_file);
fclose($count_file);

settype( $curr_count, “integer”);
$curr_count = abs($curr_count);
$curr_count++;

$count_file = fopen($count_file_path, “w”) or die(“”);
fwrite($count_file, $curr_count);
fclose($count_file);

} else {

$curr_count = false;

}

$phrases = array();

$phrases[sizeof($phrases)] = “Visitors have lost a collective.$curr_count IQ points by visiting this site.”;
$phrases[sizeof($phrases)] = “$curr_count people prefer McDonald’s to a lifetime of torture.”;
/* more phrases, etc.
the phrases take up lines 34-65
*/

$counter_phrase = ($curr_count) ? $phrases[mt_rand(0, sizeof($phrases)-1)] : “” ;

?>[/code]
