• php超全局变量


    超全局数组

    $_SERVER  查看服务器信息

    $_GET 获取get提交过来的数据 (1) 表单传值(get 方式 post 方式)(2)a标签传值

    $_POST  获取psot提交过来的数据 post提交也就是提交整个表单 表单推荐post传值

    $_REQUEST 获取a 或者表单get 或者post传过来的数据

    <?php 
       setcookie("name1",123);
       print_r($_COOKIE);
    
    ?>
    结果是
    Array ( [name1] => 123 ) 

    $_COOKIE 同一个变量在多个页面获取到

    $_SESSION  同一个变量在多个页面获取到

    <?php 
      
       $_SESSION["name"]="abc";
       print_r($_SESSION);
    ?>
    
    结果是
    Array ( [name] => abc ) 

    <?php
       $_SESSION["name1"]="abcdefg";
    session_start();
       $_SESSION["name"]="abc";
       print_r($_SESSION);
    ?>
    执行结果也是一样的
    Array ( [name] => abc ) 

    $GLOBALS 相当于把其他的全部都包含了

    <?php 
    echo "<pre>";
     print_r($GLOBALS);
    echo "</pre>";
    
    
    ?>
    结果是
    Array
    (

    $_FILES  查看上传文件的信息 以数组方式显示

    index页面
    <html>
    <head></head>
    <body>
    <form action="session.php" method="post" 
    
    enctype="multipart/form-data">
    <input type="file" name="myfile"/>
    <input type="submit" name="tj" text="提交"/>
    </form>
    </body>
    </html>
    session页面
    <?php 
    echo "<pre>";
     print_r($_FILES);
    echo "</pre>";
    ?>
    结果提交一个照片后效果如下
    Array
    (
        [myfile] => Array
