Description:
------------
When i attempted this code as follows my var_dump function returned bool(false).

However after removing the underscores from the csv file the file function worked just fine.


Reproduce code:
---------------
<?php

$line = file("april_15_05.csv");
var_dump($line);
?>

Expected result:
----------------
/** a var_dump describing the array created by file and the comma separated values */

array(50) { [0]=>  string(71) "First Name,Last Name,Weblogin,E-Mail,Pager/Cell,City,State,Webaddress " [1]=>  string(112) "firstName,lastName,fultonc2,email@*.com,number,AUGUSTA,GA,http:\\www.value.com " [2]=>  string(95) "NAOMI,HAMKE,hamken,email@*.com,,BEDFORD,IN,http:\\www.value.com

Actual result:
--------------
bool(false)
