1.怎么把php格式的文件转换为TXT格式的文本

转换txt？好像不行，不过如果想php直接用txt文件内的内容就可以

例如：<?php

readfile("hello/first.txt");

?>

或者是：<?php

$handle=fopen("hello/first.txt","r");

while(!feof($handle))

{

$buffer=fgets($handle,1024);

echo $buffer."<br>";

}

fclose($handle);

?>

2.怎么用php将excel格式转换为txt 文本

前提是你的php环境必须安装 '--enable-libxml' 组件，否则不好用。

//将bank文件夹下的bank.txt文件转换为bank.xls存到用户端。$document_ROOT = $_SERVER['document_ROOT'];$file = file("$document_ROOT/bank/bank.txt");$number_of_file = count($file); if ($number_of_file == 0) { echo ' 没有录入银行卡信息！'； exit; } for ($i = 0; $i < $number_of_file; $i++) { $row = explode(",", $file[$i]); $number_of_row = count($row); for ($k = 0; $k < $number_of_row; $k++) {//取得单元数据前，进行字符的转换，将Windows的GB2312字符转换为linux常用的UTF-8，因为在进行数据录入过程中，输入的字符时GB2312编码。

$doc[$i][$k] = iconv("GB2312","UTF-8//IGNORE",$row[$k]); } }$xls = new Excel_XML('UTF-8', false, 'My bank added Sheet');$xls->addArray( $doc );$xls->generateXML('bankadded');//php excel class source including./** *Project: 40">"; private $footer = ""; private $lines = array(); private $sEncoding; private $bConvertTypes; private $sWorksheetTitle; public function __construct($sEncoding = 'UTF-8', $bConvertTypes = false, $sWorksheetTitle = 'Table1') { $this->bConvertTypes = $bConvertTypes; $this->setEncoding($sEncoding); $this->setWorksheetTitle($sWorksheetTitle); } public function setEncoding($sEncoding) { $this->sEncoding = $sEncoding; } public function setWorksheetTitle ($title) { $title = preg_replace ("/[|:|/|?|*|[|]]/", "", $title); $title = substr ($title, 0, 31); $this->sWorksheetTitle = $title; } private function addRow ($array) { $cells = ""; foreach ($array as $k => $v): $type = 'String'; if ($this->bConvertTypes === true && is_numeric($v)): $type = 'Number'; endif; $v = htmlentities($v, ENT_COMPAT, $this->sEncoding); $cells .= "" . $v . "n"; endforeach; $this->lines[] = "n" . $cells . "n"; } public function addArray ($array) { foreach ($array as $k => $v) $this->addRow ($v); } public function generateXML ($filename = 'excel-export') { $filename = preg_replace('/[^aA-zZ0-9_-]/', '', $filename); header("Content-Type: application/vnd.ms-excel; charset=" . $this->sEncoding); header("Content-Disposition: inline; filename="" . $filename . ".xls""); echo stripslashes (sprintf($this->header, $this->sEncoding)); echo "nsWorksheetTitle . "">nn"; foreach ($this->lines as $line) echo $line; echo " nn"; echo $this->footer; } }?>。
