I am having a bit of a hard time thinking about what to do for this. I would like to display a random line from a specific text file, then after it displays it will remove that line from the text file so it will no longer show up when page refreshed.
$lines = file('');
echo $lines[array_rand($lines)];
file read lines into array. array_rand to get a random key from the array of lines. unset to remove an element. file_put_contents to write back to file.
$filename = 'filename.txt';
$lines = file($filename);
$r = array_rand($lines);
echo $lines[$r];
unset($lines[$r]);
file_put_contents($filename, implode("", $lines));
