復(fù)制代碼 代碼如下:

/**
* 得到當(dāng)前時間
*/
function getMicrotime() {

list ($usec, $sec) = explode(" ", microtime());
return ((float) $usec + (float) $sec);
}

復(fù)制代碼 代碼如下:

<?php
// This file is abc.php

include 'test1.php';
include_once 'test2.php';
require 'test3.php';
require_once 'test4.php';

$included_files = get_included_files();

foreach ($included_files as $filename) {
echo "$filenamen";
}
?>

復(fù)制代碼 代碼如下:

<?php
function myrow($id, $data)
{
return "<tr><th>$id</th><td>$data</td></tr>n";
}
$arr = get_defined_functions();
print_r($arr);
?>
