怎麼用php讀取ppt文檔的內容，並且在瀏覽器

本文實例講述了PHP讀取PPT文件的方法。分享給大家供大家參考，具體如下：

最近做一個和FLASH有關的東西，其中就要用到在網站上看PPT就像百度，豆丁網那樣可以直接在網站上讀，在網上搜了半天沒搜到，都是些什麼安裝個軟體什麼的，PHP網站放到空間上，誰能讓你在哪裝軟體呢？不是在瞎扯么？不過還好，最後在國外一個網站上搜到了一個解決思路，就是一個PHP操作PPT的類，當然這個網站還提供了操作OFFICES軟體的其他類，不過是2007版的OFFICES

下面也貼出當時看到的一個例子:

本例子使用phppowerpoint類，使用該類注意兩點，一個是了解參數含義，二注意字符集

php如何動態讀取一個文件內容？

你想無刷新顯示內容就用 ajax 實現吧，後台只負責返回這個文件的內容，前台一直不停的發送請求：

// Javascript

setInterval(function () {

    $.ajax(

        {

            url : url,         // 請求地址

            type : type,       // 請求方式

            dataType : ‘JSON’, // 返回數據的格式

            success : function (response) {

                console.log(response);  // 最終數據

            },

            error : function () {

                console.log(‘Request Fail’);

            }

        }

    );

}, 1000);

// php

$filename = ‘data.txt’;

$f = fopen($filename);

$content = fread($f, filesize($filename));

fclose($f);

echo $content;  // 具體數據格式參照前台獲取方式

用php讀取txt內容

首先fopen讀取TXT文件，獲取一個文件指針，然後fgets獲取一行，再fgets繼續讀取下一行

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);

這個前提是你的$f這個文件指針不能關閉，如果你想在不同請求的情況下實現，那就要吧$f做全局存儲了，看看存session可否(我沒做過，不確定，你試試看)

如何使用PHP讀取文本文件內容

利用PHP讀取文本文件的內容，其實很簡單，我們只需要掌握函數「file_get_contents();」的使用就可以了。下面，小編將作詳細的介紹。

工具/原料

電腦一台

WAMP開發環境

方法/步驟

file_get_content()函數介紹。使用file_get_contents()獲取txt文件的內容，具體參數說明如下：

2

具體實例說明。從文本文件tst.txt中讀取裡面的內容並顯示在瀏覽器中，具體代碼和圖示如下：

?php

$file = ‘tst.txt’;

$content = file_get_contents($file); //讀取文件中的內容

echo $content;

?

php如何讀取文本指定的內容？

php讀取文件內容:

—–第一種方法—–fread()——–

?php

$file_path = “test.txt”;

if(file_exists($file_path)){

$fp = fopen($file_path,”r”);

$str = fread($fp,filesize($file_path));//指定讀取大小，這裡把整個文件內容讀取出來

echo $str = str_replace(“\r\n”,”br /”,$str);

}

?

——–第二種方法————

?php

$file_path = “test.txt”;

if(file_exists($file_path)){

$str = file_get_contents($file_path);//將整個文件內容讀入到一個字元串中

$str = str_replace(“\r\n”,”br /”,$str);

echo $str;

}

?

—–第三種方法————

?php

$file_path = “test.txt”;

if(file_exists($file_path)){

$fp = fopen($file_path,”r”);

$str = “”;

$buffer = 1024;//每次讀取 1024 位元組

while(!feof($fp)){//循環讀取，直至讀取完整個文件

$str .= fread($fp,$buffer);

}

$str = str_replace(“\r\n”,”br /”,$str);

echo $str;

}

?

——-第四種方法————–

?php

$file_path = “test.txt”;

if(file_exists($file_path)){

$file_arr = file($file_path);

for($i=0;$icount($file_arr);$i++){//逐行讀取文件內容

echo $file_arr[$i].”br /”;

}

/*

foreach($file_arr as $value){

echo $value.”br /”;

}*/

}

?

—-第五種方法——————–

?php

$file_path = “test.txt”;

if(file_exists($file_path)){

$fp = fopen($file_path,”r”);

$str =””;

while(!feof($fp)){

$str .= fgets($fp);//逐行讀取。如果fgets不寫length參數，默認是讀取1k。

}

$str = str_replace(“\r\n”,”br /”,$str);

echo $str;

}
