1. For files that only contain php code, we will write it in the file Ignore the "?>" at the end. This is to prevent extra spaces or other characters from affecting the code. Break a new line at the end of the code file and end it with // end

<code>例：
<?php
$localtime = date('y-m-d H:i:s',time());
$test = 'test';
echo $localtime.$test;
...

// end
</code>

2. Indentation should be able to reflect the logical results of the code. Use TAB for indentation. Leave gaps (add spaces) before and after each statement and the beginning of the brace.

<code>例：
<?php
$t = date("H");

if ($t<20) {
    echo 'Have a good day!';    
} else {
    echo 'Good night';
}
...

// end
</code>
