As in the email I just sent, remember to sanitize any commands passed from the web (or anywhere, for that matter), but here are some examples. <?php $name = "Dan"; echo "Hello, my name is $name."; // Output: Hello, my name is Dan. echo 'Hello, my name is $name.'; // Output: Hello, my name is $name. echo `Hello, my name is $name.`; // Will run "Hello, my name is Dan." run as a shell command. $name = `whoami`; // Presume that your Linux web server is as user 'apache'. echo "Hello, my name is $name."; // Output: Hello, my name is apache."; echo 'Hello, my name is $name.'; // Output: Hello, my name is $name. ?> Single quotes means literal, double quotes means translatable, and backticks means executable. -- </Daniel P.
