我的一个客户有这样的需求:上传文件,可以是doc,docx,xls,pdf,txt格式,现需要用php读取这些文件的内容,然后计算文件里面字数.查了一下,大致方法如下

我的一个客户有这样的需求:上传文件,可以是doc,docx,xls,pdf,txt格式,现需要用php读取这些文件的内容,然后计算文件里面字数.

/*来首音乐吧*/

1.PHP读取DOC格式的文件

PHP没有自带读取word文件的类,或者是库,这里我们使用antiword(http://www.winfield.demon.nl/)这个包来读取doc文件.

     首先介绍一下如何在windows下使用:

      1.打开http://www.winfield.demon.nl/(antiword下载页面),找到对应的windows版本(http://www.winfield.demon.nl/#Windows),下载antiword windows版本(antiword-0_37-windows.zip);

2.将下载下来的文件解压到C盘根目录下;

这里还有一点需要注意的:http://www.informatik.uni-frankfurt.de/~markus/antiword/00README.WIN这个连接里有windows下安装的说明文件.

  需要设置环境变量,我的电脑(右键)->高级->环境变量->在上面的用户变量里新建一个

  变量名:HOME

  变量值:c:\home这个目录应该是存在的,如果不存在就在C盘下创建一个home文件夹.

然后在系统变量,修改Path,在Path变量的值最前面加上%HOME%\antiword.

 

3.开始->运行->CMD 进入到antiword目录;

      输入 antiword -h 看看效果.

 

   4.然后我们使用antiword –t 命令读取一下doc文件内容;首先复制一个doc文件到c:\antiword目录,然后执行

   >antiword –t 文件名.doc

   就可以看到屏幕上输出word文件的内容了.

可能你会问了,这和PHP读取word有什么关系呢?呵呵,别急,我们来看看如何在PHP里使用这个命令.

<?php

  $file = “D:\xampp\htdocs\word_count\uploads\doc-english.doc”;

   $content = shell_exec(“c:\antiword\antiword –f $file”);

?>

这样就把word里面的内容读取content里面了.

至于如何在Linux下读取doc文件内容,就是下载linux版本的压缩包,里面有readme.txt文件,按照那种方式安装就可以了.

$content = shell_exec ( "/usr/local/bin/antiword -f $file" );
2.PHP读取PDF文件内容 

php也没有专门用来读取pdf内容的类库.这样我们采用第三方包(xpdf).还是先做windows下的操作,下载,将其解压到C盘根目录下.

开始->运行->cmd->cd /d c:\xpdf 

<?php

   $file = “D:\xampp\htdocs\word_count\uploads\pdf-english.pdf”;

    $content = shell_exec ( "c:\\xpdf\\pdftotext $file -" );

   ?>
3.PHP读取ZIP文件内容 

首先使用PHP zip解压zip文件,然后读取解压包里的文件,如果是word就采用antiword读取,如果是pdf就使用xpdf读取.

<?php

/** 
* Read ZIP valid file 
* 
* @param string $file file path 
* @return string total valid content 
*/ 
function ReadZIPFile($file = '') { 
$content = ""; 
$inValidFileName = array (); 
$zip = new ZipArchive ( ); 
if ($zip->open ( $file ) === TR ) { 
for($i = 0; $i < $zip->numFiles; $i ++) { 
$entry = $zip->getNameIndex ( $i ); 
if (preg_match ( '#\.(txt)|\.(doc)|\.(docx)|\.(pdf)$#i', $entry )) { 
$zip->extractTo ( pathinfo ( $file, PATHINFO_DIRNAME ) . "/" . pathinfo ( $file, PATHINFO_FILENAME ), array ( 
$entry 
) ); 
$content .= CheckSystemOS ( pathinfo ( $file, PATHINFO_DIRNAME ) . "/" . pathinfo ( $file, PATHINFO_FILENAME ) . "/" . $entry ); 
} else { 
$inValidFileName [$i] = $entry; 
} 
} 
$zip->close (); 
rrmdir ( pathinfo ( $file, PATHINFO_DIRNAME ) . "/" . pathinfo ( $file, PATHINFO_FILENAME ) ); 
/*if (file_exists ( $file )) { 
unlink ( $file ); 
}*/ 
return $content; 
} else { 
return ""; 
} 
}

?>
4.PHP读取DOCX文件内容 

docx文件其实是由很多XML文件组成,其中内容就存在于word/document.xml里面.

   我们找到一个docx文件,使用zip文件打开(或者把docx后缀名改为zip,然后解压)

在word目录下有document.xml

docx文件的内容就存在于document.xml里面,我们读取这个文件就可以了.

<?php

/** 
* Read Docx File 
* 
* @param string $file filepath 
* @return string file content 
*/ 
function parseWord($file) { 
$content = ""; 
$zip = new ZipArchive ( ); 
if ($zip->open ( $file ) === tr ) { 
for($i = 0; $i < $zip->numFiles; $i ++) { 
$entry = $zip->getNameIndex ( $i ); 
if (pathinfo ( $entry, PATHINFO_BASENAME ) == "document.xml") { 
$zip->extractTo ( pathinfo ( $file, PATHINFO_DIRNAME ) . "/" . pathinfo ( $file, PATHINFO_FILENAME ), array ( 
$entry 
) ); 
$filepath = pathinfo ( $file, PATHINFO_DIRNAME ) . "/" . pathinfo ( $file, PATHINFO_FILENAME ) . "/" . $entry; 
$content = strip_tags ( file_get_contents ( $filepath ) ); 
break; 
} 
} 
$zip->close (); 
rrmdir ( pathinfo ( $file, PATHINFO_DIRNAME ) . "/" . pathinfo ( $file, PATHINFO_FILENAME ) ); 
return $content; 
} else { 
return ""; 
} 
}

?>

如果想要通过PHP创建docx文件,或者是把docx文件转为xhtml,pdf可以使用phpdocx,(http://www.phpdocx.com/)

5.PHP读TXT 

直接使用PHP file_get_content函数就可以了.

<?php

$file = “D:\xampp\htdocs\word_count\uploads\eng.txt”;

$content = file_get_content($file);

?>
6.PHP读EXCEL 

http://phpexcel.codeplex.com/

现在只是读取文件内容了,怎么计算单词的个数呢?

PHP有一个自带的函数,str_word_count,这个函数可以计算出单词的个数,但是如果要计算antiword读取出来的doc文件的单词个数就会很大的误差.

这里我们使用以下这个函数专门用来读取单词个数 

<?php

/** 
* statistic word count 
* 
* @param string $content word content of the file 
* @return int word count of the content 
*/ 
function StatisticWordsCount($text = '') { 
//    $text = trim ( preg_replace ( '/\d+/', ' ', $text ) ); // remove extra spaces 
$text = str_replace ( str_split ( '|' ), '', $text ); // remove these chars (you can specify more) 
//    $text = str_replace ( str_split ( '-' ), '', $text ); // remove these chars (you can specify more) 
$text = trim ( preg_replace ( '/\s+/', ' ', $text ) ); // remove extra spaces 
$text = preg_replace ( '/-{2,}/', '', $text ); // remove 2 or more dashes in a row 
$len = strlen ( $text ); 
if (0 === $len) { 
return 0; 
} 
$words = 1; 
while ( $len -- ) { 
if (' ' === $text [$len]) { 
++ $words; 
} 
} 
return $words; 
}

?>

详细的代码如下:

<?php 
/** 
* check system operation win or linux 
* 
* @param string $file contain file path and file name 
* @return file content 
*/ 
function CheckSystemOS($file = '') { 
$content = ""; 
//    $type = s str ( $file, strrpos ( $file, '.' ) + 1 ); 
$type = pathinfo ( $file, PATHINFO_EXTENSION ); 
//    global $UNIX_ANTIWORD_PATH, $UNIX_XPDF_PATH; 
if (strtoupper ( s str ( PHP_OS, 0, 3 ) ) === 'WIN') { //this is a server using windows 
switch (strtolower ( $type )) { 
case 'doc' : 
$content = shell_exec ( "c:\\antiword\\antiword -f $file" ); 
break; 
case 'docx' : 
$content = parseWord ( $file ); 
break; 
case 'pdf' : 
$content = shell_exec ( "c:\\xpdf\\pdftotext $file -" ); 
break; 
case 'zip' : 
$content = ReadZIPFile ( $file ); 
break; 
case 'txt' : 
$content = file_get_contents ( $file ); 
break; 
} 
} else { //this is a server not using windows 
switch (strtolower ( $type )) { 
case 'doc' : 
$content = shell_exec ( "/usr/local/bin/antiword -f $file" ); 
break; 
case 'docx' : 
$content = parseWord ( $file ); 
break; 
case 'pdf' : 
$content = shell_exec ( "/usr/bin/pdftotext $file -" ); 
break; 
case 'zip' : 
$content = ReadZIPFile ( $file ); 
break; 
case 'txt' : 
$content = file_get_contents ( $file ); 
break; 
} 
} 
/*if (file_exists ( $file )) { 
@unlink ( $file ); 
}*/ 
return $content; 
}

/** 
* statistic word count 
* 
* @param string $content word content of the file 
* @return int word count of the content 
*/ 
function StatisticWordsCount($text = '') { 
//    $text = trim ( preg_replace ( '/\d+/', ' ', $text ) ); // remove extra spaces 
$text = str_replace ( str_split ( '|' ), '', $text ); // remove these chars (you can specify more)

if (0 === $len) { 
return 0; 
} 
$words = 1; 
while ( $len -- ) { 
if (' ' === $text [$len]) { 
++ $words; 
} 
} 
return $words; 
}

return "";
