If it 's not a huge file, something like this should work

Code:

$file = "foo.txt";

$lines = file($file);

$line = mt_rand(0,count($lines)-1);
unset($lines[$line]);

$fp = fopen($file, 'w+');

foreach($lines as $line) {
    fwrite($fp,$line); 
}

fclose($fp);

With the echo bit added

Code:

$file = "foo.txt";

$lines = file($file);

$line = mt_rand(0,count($lines)-1);

echo $lines[$line];

unset($lines[$line]);

$fp = fopen($file, 'w+');

foreach($lines as $line) {
    fwrite($fp,$line); 
}

fclose($fp);
