怎么用php读取ppt文档的内容，并且在浏览器
本文实例讲述了PHP读取PPT文件的方法。分享给大家供大家参考，具体如下：
最近做一个和FLASH有关的东西，其中就要用到在网站上看PPT就像百度，豆丁网那样可以直接在网站上读，在网上搜了半天没搜到，都是些什么安装个软件什么的，PHP网站放到空间上，谁能让你在哪装软件呢？不是在瞎扯么？不过还好，最后在国外一个网站上搜到了一个解决思路，就是一个PHP操作PPT的类，当然这个网站还提供了操作OFFICES软件的其他类，不过是2007版的OFFICES
下面也贴出当时看到的一个例子:
本例子使用phppowerpoint类，使用该类注意两点，一个是了解参数含义，二注意字符集

php如何动态读取一个文件内容？
你想无刷新显示内容就用 ajax 实现吧，后台只负责返回这个文件的内容，前台一直不停的发送请求：
// Javascript
setInterval(function () {
$.ajax(
{
url : url, // 请求地址
type : type, // 请求方式
dataType : 'JSON', // 返回数据的格式
success : function (response) {
console.log(response); // 最终数据
},
error : function () {
console.log('Request Fail');
}
}
);
}, 1000);
// php
$filename = 'data.txt';
$f = fopen($filename);
$content = fread($f, filesize($filename));
fclose($f);
echo $content; // 具体数据格式参照前台获取方式
用php读取txt内容
首先fopen读取TXT文件，获取一个文件指针，然后fgets获取一行，再fgets继续读取下一行
官方例子：
?php
$f = fopen ("fgetstest.php", "r");
$ln= 0;
while (! feof ($f)) {
$line= fgets ($f);
++$ln;
printf ("%2d: ", $ln);
if ($line===FALSE) print ("FALSE\n");
else print ($line);
}
fclose ($f);
这个前提是你的$f这个文件指针不能关闭，如果你想在不同请求的情况下实现，那就要吧$f做全局存储了，看看存session可否(我没做过，不确定，你试试看)
如何使用PHP读取文本文件内容
利用PHP读取文本文件的内容，其实很简单，我们只需要掌握函数“file_get_contents();”的使用就可以了。下面，小编将作详细的介绍。
工具/原料
电脑一台
WAMP开发环境
方法/步骤
file_get_content()函数介绍。使用file_get_contents()获取txt文件的内容，具体参数说明如下：
2
具体实例说明。从文本文件tst.txt中读取里面的内容并显示在浏览器中，具体代码和图示如下：
?php
$file = 'tst.txt';
$content = file_get_contents($file); //读取文件中的内容
echo $content;
?
php如何读取文本指定的内容？
php读取文件内容:
-----第一种方法-----fread()--------
?php
$file_path = "test.txt";
if(file_exists($file_path)){
$fp = fopen($file_path,"r");
$str = fread($fp,filesize($file_path));//指定读取大小，这里把整个文件内容读取出来
echo $str = str_replace("\r\n","br /",$str);
}
?
--------第二种方法------------
?php
$file_path = "test.txt";
if(file_exists($file_path)){
$str = file_get_contents($file_path);//将整个文件内容读入到一个字符串中
$str = str_replace("\r\n","br /",$str);
echo $str;
}
?
-----第三种方法------------
?php
$file_path = "test.txt";
if(file_exists($file_path)){
$fp = fopen($file_path,"r");
$str = "";
$buffer = 1024;//每次读取 1024 字节
while(!feof($fp)){//循环读取，直至读取完整个文件
$str .= fread($fp,$buffer);
}
$str = str_replace("\r\n","br /",$str);
echo $str;
}
?
-------第四种方法--------------
?php
$file_path = "test.txt";
if(file_exists($file_path)){
$file_arr = file($file_path);
for($i=0;$icount($file_arr);$i++){//逐行读取文件内容
echo $file_arr[$i]."br /";
}
/*
foreach($file_arr as $value){
echo $value."br /";
}*/
}
?
----第五种方法--------------------
?php
$file_path = "test.txt";
if(file_exists($file_path)){
$fp = fopen($file_path,"r");
$str ="";
while(!feof($fp)){
$str .= fgets($fp);//逐行读取。如果fgets不写length参数，默认是读取1k。
}
$str = str_replace("\r\n","br /",$str);
echo $str;
}
?
