一.建立模板：
將頁面中經常出現的部分複製到一個html或php檔案中，在原頁面中用require()/include()函數引入。
例子：
源html：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base> <body> <form action="handle.php" method="post"> <p> Name:<select name="title"> <option value="Mr">Mr</option> </select> <input type="text" name="name" size="20"/></p> <input type="submit" value="send"></form><div><p>This is the foot of the document</p></div></body> </html>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>test</title><base> <body>
<div><p>This is the foot of the document</p></div></body> </html>
<?phprequire('header.html');?><form action="handle.php" method="post"> <p> Name:<select name="title"> <option value="Mr">Mr</option> </select> <input type="text" name="name" size="20"/></p> <input type="submit" value="send"></form><?phprequire('footer.html');?>
二、處理表單——讓一個頁面同時顯示和處理表單
使用條件陳述式：
if (表單提交) { 處理表單 }
else { 顯示表單 }
例子：簡單的 使用者名稱-密碼驗證
輸入：使用者名稱：YF 密碼：123456
顯示：登陸成功
裁圖：
代碼：ws.php(其中header.html、footer.html引用的是上文中的模板）：
<?phpdefine('TITLE', 'Login');require('header.html');if (isset($_POST['submitted'])) {if ((!empty($_POST['name'])) && (!empty($_POST['password']))){if ((strtolower($_POST['name']) == 'yf') && ($_POST['password'] == '123456')){// name and password are correct.print '<p> logged in !</p>';}else {print '<p> name or password is worry!</p>';}}else {print '<p> make sure you enter both name and password!</p>';}}else {print '<form action="ws.php" method="post"> <p> Name:<input type="text" name="name" size="20"/></p> <p>Password:<input type="password" name="password" "size="20" /></p> <input type="submit" value="send"> <input type="hidden" name="submitted" value="true"/></form>';}require('footer.html');?>
