一、PHP的基本结构:
使用Include函数
<Html>
<Head>
<title>Your page Subject and domain name</title>
上面内容为我们使用的每个页面的标题,不要动。
每个页的头部:
<Meta NAME="" CONTENT="">
"" your others meta tag
"" your others meta tag
"" your others meta tag
"" your others meta tag
"" your others meta tag
"" your others meta tag
"" your others meta tag
重要的javascripts代码放这
CSS设置放这
上述内容保存为header.php,使每个页面的头部都是一样的。
<?PHP include("header.php")?>
</head>
<body>
你的页的所有内容
</body>
</html>
保存为footer.php,使每个页面的底部都一样。
<? include("footer.php");?>
填写我们的版权信息
</body>
</html>
二:如何输出文本或者把文本建立连接用PHP
在PHP中如何显示文本呢?使用下面的命令:
<?php echo "Hello in php";?>
如何创建一个连接呢?
<?php echo "<a href=\"http://www.webjx.com\">www.webjx.com.com</a>";?>
如何创建一个有style的连接呢?
<?php echo "<font style=\"color:blue;font-size:10px;font- family:verdana;\">Free Scripts By: <a href=\"http://www.webjx.com.com\" target=\"_blank\" title=\"Free Scripts By: webjx.com\">http://www.webjx.com<;/font></a>";?>
"echo"是用来显示输出的。
三:如何实现分页:
如果好多内容在你的页面中这时我们就考虑用分页形式来实现显示了。
简单的分页代码:
<html>
<head>
<title>webjx.com</title>
</head>
<body text="#000000">
<center>
<table width="500" border="3">
<tr>
<td width="140" height="400" valign="top">
<p align="center">
<a href='index.php'>home</a><br />
<a href='index.php?p=Page1'>page 1</a><br />
<a href='index.php?p=Page2'>page 2</a><br />
</p></td>
<td width="360" height="400" valign="top">
<p>
<?
function index()
{
echo "<p align=center>Welcome to this tutorial<br />Here you can find funny
tricks</p><br /><br /><br /><br /><br /><br />"; }
$choice=$_GET['p'];
switch($choice)
{
case "Page1":
echo "<p align=center>Page1 text, img and so on here</p>";
break;
case "Page2":
echo "<p align=center>Page2 text, img and so on here</p>";
break;
default:
index();
}
?>
</p>
</td>
</tr>
</table> </center>
</body>
</html>
以上文件必须保存为index.php
高级分页的代码:
<html>
<head>
<title>webjx.com</title>
</head>
<body text="#000000">
<center>
<table width="500" border="3">
<tr>
<td width="140" height="400" valign="top">
<p align="center">
<a href='index.php'>home</a><br />
<a href='index.php?action=contact_us'>page 1</a><br />
<a href='index.php?action=link_us'>page 2</a><br />
</p></td>
<td width="360" height="400" valign="top">
<p>
<?
if (isset($_GET['action'])) $PAGE = $_GET['action'];
else $PAGE = 'home';
switch ($PAGE) {
//1- index
case 'home':
include ('incl/home.php');
break;
//2-contact form
case 'contact_us':
include ('incl/contact_us.php');
break;
//3-Link us
case 'link_us':
include ('incl/link_us.php');
break;
default:
echo '<p align=center>Error 404! the page you request doesn t exist or as been temporarely unaccessible</p>';
break;
}
?>
</p>
</td>
</tr>
</table>
</center>
</body>
</html>

四:页面加载时间的代码:
<?php
echo ("Page Took :");
$load = microtime();
print (number_format($load,2));
echo (" Sec To Load.");
?>
五:显示从哪个地址转到你当前访问的站的代码:
<?php
echo "You Came From:<br />";
echo $_SERVER['HTTP_REFERER'];
?>
六:设置IP地址的转向:屏蔽IP
<?php
if(($REMOTE_ADDR == "22.22.22.22")):// ip address
print "<meta http-equiv='refresh' content='0; url=http://www.sina.com'>";// url to redicted
endif;
?>
七:随即显示标题的代码:
<Title><?php include("title.php");?></Title>
要事先做一个title.php文件啊
八;如何用PHP来建立一个HTML 的table
<?php
echo"<html>\n";
echo"<head>\n";
echo"<title>allo</TITLE>\n";
echo"</head>\n";
echo"<body topmargin=\"0\" leftmargin=\"0\" rightmargin=\"0\" bottommargin=\"5\"
bgcolor=\"#ffffff\">\n";
echo"<center>\n";
echo"<table width=\"500\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\">\n";
echo"<tr>\n";
echo"<td>\n";
echo"<p align=\"center\">\n";
echo"
\n";
echo"Text Goes Here\n";
echo"</p>\n";
echo"</td>\n";
echo"</tr>\n";
echo"</table>\n";
echo"</center>";
echo"</body>\n";
echo"</html>";
?>
九、声明字符串变量:
建立一个页面 ( config.php ) 粘贴下面代码:
<?
$name="Name";
$salutation="Hey!";
$title="webjx.com";
$copyrights="©2005 webjx.com";
$link_1="Home";
?>
创建一个页面( test.php )把下列代码
<? include("config.php");?>
放在<html><head>之前,然后在test.php页里来调用上面的字符串
<p align="center"><? echo("$title");?></p>
也可以这样来声明:
<?
$surname1="Marco"; $lastname1="Charette";
?>
调用:
<? echo("$surname1 $lastname1");?>
十、显示你的服务器的信息:
<? phpinfo(); ?>
十一:实现页面的跳转:
创建"jump.php"页面并且设置变量来隐藏连接的地址
<?
if ($id == "1"){$link = "http://webjx.com";}
if ($id == "2"){$link = "http://google.com";}
header("Location: $link"); // 实现了跳转
exit();
?>
保存之后,在另外一个页中加入如下代码:
<a href="jump.php?id=1">Visit This Link</a>
跳转并且还把访客保存在你的页面内:
<?
if ($id == "1"){$link = "http://webjx.com";}
if ($id == "2"){$link = "http://google.com";}
echo "<frameset rows=\"0,100%\" border=\"0\">\n";
echo "<frame src=\"jump.php\" name=\"head\" scrolling=\"no\" marginheight=\"0\" frameborder=\"0\" noresize>\n";
echo "<frame src=\"$link\" name=\"body\" marginheight=\"10\" marginwidth=\"10\" frameborder=\"0\" noresize>\n";
echo "</frameset>\n";
header("Location: $link");
exit();
?>
保存为jump.php然后再其他页内加入连接代码:
<a href="jump.php?id=1">Visit This Link</a>
十二、保护页面:
<? $Referer = getenv("HTTP_REFERER");
if (!strchr($Referer, "http://webjx.com/page.php")) {
echo "<script>alert('你不能访问这个页面');
window.location='http://webjx.com';</script>";
exit(); } ?>
十三:限制访问某个页面
// choose a user name and password between the " " symbol
//===========================
$admin_user_name="admin"; // your admin username
$admin_password="pass"; // your password
$site_com="webjx.com"; // your website name WITHOUT http:// and www
$login="你已经登陆"; // succesful message when user are logged in ( NOT NECESSARY )
//===========================
// DO NOT EDIT NOTHING BELOW!
if ((!isset($PHP_AUTH_USER)) || (!isset($PHP_AUTH_PW))) {
/* No values: send headers causing dialog box to appear */
header('WWW-Authenticate: Basic realm="$site_com"');
header('HTTP/1.0 401 Unauthorized');
echo '<h1>访问的页面被限制.</h1>请检查你的用户名或密码是否正确,正常登陆本站才能查看 本站的内容';
exit;
} else if ((isset($PHP_AUTH_USER)) && (isset($PHP_AUTH_PW))){
/* Values contain some values, so check to see if they're correct */
if (($PHP_AUTH_USER != "$admin_user_name") || ($PHP_AUTH_PW != "$admin_password")) { /* If either the username entered is incorrect, or the password entered is incorrect, send the headers causing dialog box to appear */
header('WWW-Authenticate: Basic realm="$site_com"');
header('HTTP/1.0 401 Unauthorized');
echo '<h1>访问的页面被限制.</h1>请检查你的用户名或密码是否正确,正常登陆本站才能查看 本站的内容';
exit;
} else if (($PHP_AUTH_USER == "$admin_user_name") || ($PHP_AUTH_PW == "$admin_password")) { echo "$login<br />";
}
}
?>
保存为log.php,把下列代码加到head页内,那么将会保护所有的页面。
<? require("log.php");?>
十四、制作一个自动转向:
<?php
header("Refresh:0; url=http://webjx.com");
?>
必须保存为php文件才可以。
十五。制作用户列表:
<?
$customer[0] = 'webjx';
$customer[1] = 'web';
$customer[2] = 'mutou';
$customer[3] = 'chuxia';
$customer[4] = 'shenhua';
echo "第3个用户是: $customer[2]";
echo "<br /><br />所有的用户:<br /><br />";
$number = 5;
$x = 0;
while ($x < $number) {
$customernumber = $x + 0;
echo "Costumer Name $customernumber is $customer[$x]<br />";
++$x;
}
?>
将会显示:
The third customer is mutou
所有的用户:
Costumer Name 0 is webjx
Costumer Name 1 is web
Costumer Name 2 is mutou
Costumer Name 3 is chuxia
Costumer Name 4 is shenhua
另一种读取数组的方法:
<?
echo "3 of my customer are: $customer[0], " . " $customer[1] and " . " $customer[2]. " . "<br />";
?>
将会显示:
3 of my customer are: webjx, web and mutou.
十六.统计某个目录下文件的数量:
<?
echo("There is ");
$dir = "/path/to/the/folder/in/your/computer ";
$count = 0;
$handle=opendir($dir);
while (($file = readdir($handle))!== false){ if ($file != "." && $file != "..") { $count++; }}
echo $count;
echo(" Pages For You To Search In This Directory.");
?>
十七.显示当前日期或最新更新的日期:
<?php echo date("F d Y"); ?>
显示更新日期:
<?php echo "Last Modified: " . date ("m/d/y.", getlastmod());?>
十八.重复一个字符多次的代码:
<?
echo str_repeat("-", 30);
?>
