Walking Randomly

I don’t know very much about PHP. In fact it is probably more accurate to say that I don’t know anything about programming in PHP and yet, earlier today, I found myself in need of being able to type in simple PHP scripts and run them on the command line. A quick google search later and I find that I need to issue the following command in Ubuntu

apt-get install php5-cli

Now I can write little scripts like this one (which I called md5.php) and run them on the command line

#!/usr/bin/php -q
<?php
$arg=$_SERVER["argv"][1];
echo md5($arg),”\n”;
?>

./md5.php hello

I mention it because I might forget about it and looking up on here is quicker for me than googling it.
