php目录文件在线解压缩程序
本文章提供一款完整的php目录 文件在线解压缩程序，他可打包指定目录并且把目录下所有目录与文件名都打包好,按rar的方式打包,目录结构不变,同时也提供解压功能.代码如下:
$fz = new fmzip; $fz ->setzipname( "打包文件名" ); #打包/压缩 $fz ->setsource( "待打包目录" ); $fz ->compress( $silent , $compress ); #解包/解压 $fz ->settarget( "待解包目录" ); $fz ->uncompress( $silent ); */ class fmzip { var $source ; //压缩源 var $target ; //解压目的文件夹 var $zipname ; //压缩文件名 var $handle ; //打开压缩文件的句柄 var $silent ; //是否输出 var $count_dir ; //计数器_文件夹 var $count_file ; //计数器_文件 var $dirlist ; function setsource( $source ) //设置压缩源 { if (! file_exists ( $source )) die ( "source <$source> does not exist." ); $this ->source = $source ; } function settarget( $target ) //设置解压目的文件夹 { if (! file_exists ( $target )) $this ->makedir( $target ); chdir (dirname( $_server [ 'script_filename' ])); if ( substr ( $target ,-1)== "/" ) $target = substr ( $target ,0, strlen ( $target )-1); if (! file_exists ( $target )) { die ( "target <$target> does not exist." ); } $this ->target = $target ; } function setzipname( $zipname ) //设置压缩文件名 { if ( empty empty ( $zipname )) $zipname = "fmzip.fz" ; $this ->zipname = $zipname ; } function compress( $silent = false, $compress = true) //压缩 { $this ->silent = $silent ; if ( $silent ===false) echo "<pre>compressing...rn" ; if ( is_file ( "$this->zipname" ))unlink( "$this->zipname" ); $this ->handle = fopen ( $this ->zipname, "w" ); //创建压缩文件 if ( $this ->handle == null) die ( "error creating $this->zipname" ); //打开失败 $this ->count_dir = 0; $this ->count_file = 0; //初始化计数器 $this ->merge( $this ->source); //压缩 fwrite( $this ->handle, "-1" ); //结束标志 fclose( $this ->handle); //关闭文件 echo "rndirectory: $this->count_dir" ; echo "rnfile: $this->count_filern" ; if (function_exists( "gzcompress" ) && $compress ==true) { file_put_contents ( "$this->zipname.gz" ,gzcompress( file_get_contents ( "$this->zipname" ))); unlink( "$this->zipname" ); } if ( $silent ===false) { echo $this ->listfile(); echo "</pre>" ; } } function listfile() { if ( file_exists ( "$this->zipname.gz" )) return "<a href=" $this ->zipname.gz " target=" _blank ">download $this->zipname.gz</a>" ; if ( file_exists ( "$this->zipname" )) return "<a href=" $this ->zipname " target=" _blank ">download $this->zipname</a>" ; } function merge( $dir ) //合并文件、文件夹(递归) { /* 说明：不处理link。 */ if ( is_dir ( $dir )) //如果压缩源是文件夹 { $list = scandir( $dir ); //扫描文件列表 natcasesort( $list ); foreach ( $list as $file ) //先处理文件夹 { $full = "$dir/$file" ; if (! is_dir ( $full )|| $file == "." || $file == ".." ) continue ; //只处理文件夹 $this ->count_dir++; if ( $this ->silent===false) echo "[dir] $fullrn" ; //输出提示 fwrite( $this ->handle, $this ->file_info( $full )); //写入文件夹信息 $this ->merge( $full ); //递归合并下级文件夹 } //文件夹处理完毕; foreach ( $list as $file ) //处理文件 { $full = "$dir/$file" ; if (! is_file ( $full )|| $file == "." || $file == ".." ) continue ; //只处理文件 $this ->count_file++; if ( $this ->silent===false) echo "[file] $fullrn" ; //输出提示 fwrite( $this ->handle, $this ->file_info( $full )); //写入文件信息 } //文件处理完毕 } else { $this ->count_file++; if ( $this ->silent===false) echo "[file] $fullrn" ; //输出提示 fwrite( $this ->handle, $this ->file_info( $file )); //写入文件信息 } } //end function merge function file_info( $file ) { $perm = substr (sprintf( '%o' , fileperms ( $file )), -3); //权限 $filename = str_replace ( $this ->source, "" , $file ); if ( is_file ( $file )) //文件 { $size = filesize ( $file ); //文件大小 return "1rn$filenamern$permrn$sizern" . file_get_contents ( $file ).
