PHP入门

先来看看效果代码如下

header实现302临时重定向

header实现404无法找到页面

ob_end_clean(); //清除输出缓存并且关闭缓存
echo str_pad(' ',256);//输出256字节空格（在ie浏览器下要接受大于256个字节才会输出显示
）

该方法在opera下不可用，因为opera浏览器在不遇到一个html标签之前是不输出内容的

/**
 * 循环实现编码互转
 *
 * @param string $param(字符串，对象，或者数组)，$currCharset当前编码，$toCharset期望编码
 * @return 参数类型
 */
function zhandi_iconv($param,$currCharset,$toCharset){
 if ($currCharset != $toCharset){
  if (is_string($param)){
   return iconv($currCharset, $toCharset, $param);
  }
  elseif (is_array($param)){
   foreach ($param as $key => $value){
    $param[$key] = zhandi_iconv($value);
   }
   return $param;
  }
  elseif (is_object($param)){
   foreach ($param as $key => $value){
    $param->$key = zhandi_iconv($value);
   }
   return $param;
  }
  else{
   return $param;
  }
 }
 return $param;
}

一、             基本概念

1、  PDO：PHP Data Object的缩写。PDO扩展类库为PHP定义了一个轻量级的、一致性的接口，它提供了一个数据访问抽象层，这样无论使用什么数据库，都可以通过一致的函数执行查询和获取数据。

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<?php

//测试

 

<?php
function removeDir($dirName)
{
    if(! is_dir($dirName))
    {
        return false;
    }
    $handle = @opendir($dirName);
    while(($file = @readdir($handle)) !== false)
    {
        if($file != '.' && $file != '..')
        {
            $dir = $dirName . '/' . $file;
            is_dir($dir) ? removeDir($dir) : @unlink($dir);
        }
    }
    closedir($handle);
 
    return rmdir($dirName) ;
}
?>

本文章介绍了一篇php中时间日期转换自定函数，它可以实现将秒数表示的事件转换为年、月、日、小时等时间格式。  代码如下 复制代码 function Sec2Time($time){if(is_numeric($time)){$value = array("years" => 0, "days" => 0, "hours" => 0,"minutes" => 0, "seconds" => 0,);i...
