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.
