If the file is of a reasonable size (not hundreds of kilobytes), then you
can just slurp it all into an array and foreach through it:
$matched = 0;
$myfile = file('/usr/home/crud/myfile');
foreach ($myfile as $line)
{
$split_line = explode(':', $line);
if ($split_line[1] == 'bob')
{
echo '<p>Got a match!</p>';
$matched = 1;
break;
}
}
if (!$matched)
echo '<p>Username not found.</p>';
If it's larger, you're doing it an awful lot, or your server is
resource-cramped, you'd probably want to fopen() it and loop over fgets()
so you don't have to read in any more than necessary.
