Executing UNIX command from PHP script

How can I execute a UNIX command from a PHP script?

Is there someway of doing the following:

PHP Code:
echo "<HTML>";
     echo `
uname -a`;         <=== How do you execute this?

This is what I am using.

But I do have another question, how can I set the PATH for commands?

For example,

If I run "php -f test.php"

PHP Code:
echo '<pre>';

// Outputs all the result of shellcommand "ls", and returns
// the last output line into $last_line. Stores the return value
// of the shell command in $retval.
$last_line system('ls'$retval);

// Printing additional info
echo '
<hr />Last line of the output: ' 
$last_line '
<hr />Return value: ' 

the result is:
sh: /usr/local/php/bin/ls: No such file or directory
