Save yourself some grief and use the file() function instead.
$filename = "test";
$fileData = file($filename);
for ($i = 0; $i < count($fileData); $i++)
{
$output = substr($fileData[$i], 0, strpos($fileData[$i], ":"));
echo $output;
}
strpos will work fine for this assuming the users don't have a : in
their username! Otherwise it'll return the first occurrence of it
within the string.
If it doesn't echo anything out, the file() function failed.
Warning: above not tested, just typed direct into this email. But
baring obvious syntax errors I might have typo'd, it should work.
