 * base_convert  在随机进制之间转移数字
 * fileperms  得到文件的权能
 */
// 获取权力

为大家介绍二个 php 生成 导出word(可含蓄图表卡塔尔(قطر‎的代码,有须要的敌人可以参谋下。

 代码如下

事情未发生前介绍过php生成word的例子,只是无法包涵图表与链接。

<?php
echo fileperms("test.txt");
?>

今天 为大家介绍二个 php 生成 导出word(可含蓄图表卡塔尔(قطر‎的代码,有亟待的朋友能够参谋下。
1、生成word的类 docclass.php:

复制代码代码示例:

<?php
/***********************************************************************
Class: Mht File Maker
Version: 1.2 beta
Link:www.jbxue.com
Author: Wudi <wudicgi@yahoo.de>
Description: The class can make .mht file.
***********************************************************************/

例子2

class MhtFileMaker{
var $config = array();
var $headers = array();
var $headers_exists = array();
var $files = array();
var $boundary;
var $dir_base;
var $page_first;

 代码如下

function MhtFile($config = array()){

/*
 * substr 重回字符串的子串
 * base_convert  在随性所欲进制之间转变数字
 * fileperms  获得文件的权柄
 */
// 获取权力
function getChmod($filepath){

}

function SetHeader($header){

}

}

} else {

}
}

function SetBaseDir($dir){

}
}
}

}

function AddFile($filename, $filepath = NULL, $encoding = NULL){
if ($filepath == NULL) {

function CheckFiles(){

2、导出word文件 exportdoc.php  

复制代码代码示例:

<?php 
/**
* 依据HTML代码获取word文书档案内容
* 创设多个真相为mht的文书档案,该函数会分析文件内容并从远程下载页面中的图片能源
* 该函数看重于类MhtFileMaker
* 该函数会剖判img标签,提取src的属性值。不过,src的属性值必需被引号包围,不然无法领到

* @param string $content HTML内容
* @param string $absolutePath 网页的相对路线。假诺HTML内容里的图片路线为相对路线,那么就须求填写那些参数,来让该函数自动增加补充成相对路径。那一个参数最终索要以/结束
* @param bool $is伊RusseLink 是还是不是去掉HTML内容中的链接
*/
include_once("docclass.php"); 
function getWordDocument( $content , $absolutePath = "" , $isEraseLink = true )
{
$mht = new MhtFileMaker();
if ($isEraseLink)
$content = preg_replace('/<as*.*?s*>(s*.*?s*卡塔尔(قطر‎</a>/i' , '$1' , $content卡塔尔; //去掉链接

$images = array();
$files = array();
$matches = array();
//这一个算法须要src后的属性值必需利用引号括起来
if ( preg_match_all('/<img[.n]*?srcs*?=s*?["'](.*?)["'](.*?)/>/i',$content ,$matches ) )
{
$arrPath = $matches[1];
for ( $i=0;$i<count($arrPath);$i++)
{
$path = $arrPath[$i];
$imgPath = trim( $path );
if ( $imgPath != "" )
{
$files[] = $imgPath;
if( substr($imgPath,0,7) == 'http://')
{
//绝对链接,不加前缀
}
else
{
$imgPath = $absolutePath.$imgPath;
}
$images[] = $imgPath;
}
}
}
$mht->AddContents("tmp.html",$mht->GetMimeType("tmp.html"),$content);

for ( $i=0;$i<count($images);$i++)
{
$image = $images[$i];
if ( @fopen($image , 'r') )
{
$imgcontent = @file_get_contents( $image );
if ( $content )
$mht->AddContents($files[$i],$mht->GetMimeType($image),$imgcontent);
}
else
{
echo "file:".$image." not exist!<br />";
}
}

return $mht->GetFile();
}
$content=implode("",file(""));
$fileContent = getWordDocument($content,".");
$fp = fopen("hugesky_word.doc", 'w');
fwrite($fp, $fileContent);
fclose($fp); 
?>
