Constants are generally composed of capital letters, constants can only be defined once

bool define ( string name, mixed value [, bool case_insensitive] )
bool defined ( string name )

<?php
echo "中文测试<br/>";
print "hello world!"; echo "<br/>"; echo "<img src='/test/a.jpg'></img>"; define("PI",3.14); var_dump(defined("Pi")); echo PHP_OS; echo "<br/>"; echo PHP_VERSION; echo "<br/>"; echo __FILE__; ?>

Naming constants, variables:
the letters, begins with an underscore, followed by letters, numbers, underscores

Beginning at $ named variables, variable assignment after first use of
the same variable, which can store digital can also store the string, that is, you can store any type of data
in order to use the variables do not specify a data type, but must be assigned

Seeking string length: int strlen (string character name)
substring position to find the first occurrence of: int strpos
Find position of last occurrence of a substring of: int strrpos

Find the right character string composed of n substring
substr (original string, - $ n) or: substr (original string, strlen (original string) - $ n)

Strips the filename extension

$dotpos = strpos($fileName,".");
echo substr($fileName,0, $dotpos);
$y = $x++ 相当于｛$y=$x; $x=$x+1;｝ $y = $x-- 相当于｛$y=$x; $x=$x-1;｝ $y = ++$x 相当于｛$x=$x+1; $y=$x;｝ $y = $x-- 相当于｛$x=$x-1; $y=$x;｝
对于表达式：A && B，如果A为假，则不再计算表示式B的值
对于表达式：A || B，如果A为真，则不再计算表示式B的值

PHP Date() 函数可把时间戳格式化为可读性更好的日期和时间

语法

date(format,timestamp)
d - 月中的天 (01-31) 
m - 当前月，以数字计 (01-12) Y - 当前的年（四位数） 
<?php 
  echo date("Y/m/d"); 
  echo "<br />"; echo date("Y.m.d"); echo "<br />"; echo date("Y-m-d"); ?>

PHP 引用文件
include() 或 require()
它们处理错误的方式不同
include() 函数会生成一个警告
require() 函数会生成一个致命错误

PHP 文件处理

fopen ( string $filename , string $mode )

关闭文件

fclose() 函数用于关闭打开的文件

逐行读取文件

fgets() 函数用于从文件中逐行读取文件

PHP 文件上传

<html> <body> 
  <form action="upload_file.php" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html>

标签的 enctype 属性规定了在提交表单时要使用哪种内容类型。在表单需要二进制数据时，比如文件内容，请使用 “multipart/form-data”。

 标签的 type=“file” 属性规定了应该把输入作为文件来处理。

PHP 的全局数组 $_FILES，存放了上传到服务器的文件的所有信息

$_FILES["file"]["name"] - 被上传文件的名称 
$_FILES["file"]["type"] - 被上传文件的类型 
$_FILES["file"]["size"] - 被上传文件的大小 $_FILES["file"]["tmp_name"] - 存储在服务器的文件的临时副本的名称 $_FILES["file"]["error"] - 由文件上传导致的错误代码

“upload_file.php”文件

<?php if ($_FILES["file"]["error"] > 0) { 　echo "Error: " . $_FILES["file"]["error"] . "<br />"; } else { 　echo "Upload: " . $_FILES["file"]["name"] . "<br />"; 　echo "Type: " . $_FILES["file"]["type"] . "<br />"; 　echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />"; 　echo "Stored in: " . $_FILES["file"]["tmp_name"]; } ?>

保存被上传的文件

<?php
 if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg")) && ($_FILES["file"]["size"] < 20000)) { if ($_FILES["file"]["error"] > 0) { echo "Return Code: " . $_FILES["file"]["error"] . "<br />"; } else { if (file_exists("upload/" . $_FILES["file"]["name"])) { echo $_FILES["file"]["name"] . " already exists. "; } else { move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; } } } else { echo "Invalid file"; } ?>

编码方案

<?php header(‘Content-type: text/html; charset=gbk’);?>//放在php文档的头部
<meta http-equiv= "Content-Type" content=" text/html; charset=UTF-8">

编码的转换

string iconv ( string $in_charset , string $out_charset , string $str )

什么是 Cookie？
Cookies-在客户端保存信息

cookie 常用于识别用户。cookie 是服务器留在用户计算机中的小文件。每当相同的计算机通过浏览器请求页面时，它同时会发送 cookie。通过 PHP，您能够创建并取回 cookie 的值。

如何创建 cookie？
setcookie() 函数用于设置 cookie。

语法

setcookie(name, value, expire, path, domain);

如何删除 cookie？

<?php       // set the expiration date to one hour ago setcookie("user", "", time()-3600);
 ?>

Session-在服务器端保存用户信息

PHP session 变量用于存储有关用户会话的信息，或更改用户会话的设置。

Session 的工作机制是：为每个访问者创建一个唯一的 id (UID)，并基于这个 UID 来存储变量。UID 存储在 cookie 中，亦或通过 URL 进行传导。

Session 生命周期

Before the start tag session_start () function must be located

Session variables stored
using PHP $ _SESSION variable

<?php session_start(); $_SESSION['views']=1; ?> <?php echo "Pageviews=". $_SESSION['views']; ?>

isset (variable): determine whether a variable has been set.
unset (): function used to free a session variable
session_destroy () function is a complete end session

PHP mail () function
PHP mail () function is used to send e-mail from a script

The easiest way is to send a text email

<?php
　　$to = "[email protected]"; 
　　$subject = "Test mail"; 　　$message = "Hello! This is a simple email message."; 　　 $from = "[email protected]"; 　　$headers = "From: $from"; 　　mail($to,$subject,$message,$headers); 　　 echo "Mail Sent."; ?>

mailform.php

<?php 
if (isset($_REQUEST['email'])) { 　　 $email = $_REQUEST['email'] ; 　　$subject = $_REQUEST['subject'] ; 　　$message = $_REQUEST['message'] ; 　　mail( "[email protected]", "Subject: $subject", $message, "From: $email" ); 　　echo "Thank you for using our mail form"; } else { 　　echo "<form method='post' action='mailform.php'> 　　Email: <input name='email' type='text' /><br /> 　　Subject: <input name='subject' type='text' /><br /> 　　Message:<br /> <textarea name='message' rows='15' cols='40'> </textarea><br /> 　　<input type='submit' /> </form>"; } ?>

PHP exception handling

Initiative to throw an exception:
the throw exception objects;

Catch the exception

 try { 
　　这是放可能产生异常的语句。
 }  catch(Exception $e)
 {
    　异常的处理语句；   
}
<?php
foreach($_COOKIE as $key=>$value){
    setCookie($key,"",time()-60); } echo "删除所有cookie!";
