help for php regular expression?

[ALVIN]

here is my code and my reg ex:

<?php
$f = fopen ("LowLevelLogs.txt", "r");
$ln= 0;
while ($line= fgets ($f)) {
++$ln;
//printf ("%2d: ", $ln);
if ($line===FALSE) {
echo ("FALSE\n");
}
else {
if (preg_match("/TEST/", $line, $matches)) {
echo $matches[0]."<br>";
}
}
}
fclose ($f);
?>

the problem is that i want to print the whole line that matches the reg ex.
Here is the text file:
