PHP中，从数据库取出几条数据，如何先生成xls文件，然后保存到指定文件夹下面？

Q1: php将数据写入文件

使用form表单post数据到PHP，然后用file_put_contents($fileName, $data)写入文件，$fileName是文件名，$data是要写入的数据

新建一个a.php文件，将下面的复制进去访问一下，填写后点击提交，会生成一个a.txt的文件，里面是你填写的内容

可能会有一个notice的报错，不必理会

?php

$data = $_POST['text'];

$fileName = 'a.txt';

file_put_contents($fileName, $data);

?

!doctype html

html

head

meta charset="utf-8"

titletest/title

/head

body

form action="./a.php" method="post"

textarea name="text" id="" cols="30" rows="10"/textarea

input type="submit" value="提交"

/form

/body

/html

Q2: 求PHP从数据库中读取内容并存入文件和从文件读取数据插入数据库的代码

//第一种 

?php

$conn = mysql_connect("主机名","用户名","密码");

mysql_select_db("数据库名",$conn);

$sql = "select * from user";

$result = mysql_query($sql);

$data="";

while($row = mysql_fetch_row($result)){

    foreach($row as $v){

        $data .=$v."|";      //加个树线隔开字段

    }

    nl2br($data);    //读完一行回车

}

file_put_contents("abc.txt",$data);

//第二种

?php

$filename = "abc.txt";

$res = fopen($filename,"r");

while(!feof($res)){

$buffer = fgets($res);

$buffer = str_replace(' ', '|', $buffer); 

$array = explode('|', $buffer); 

foreach($array as $v){

if(strlen($v)0){

$arr[] = $v;

}

}

}

fclose($res);

//组装数组插入数据库就可以了

Q3: 关于PHP文件操作: php保存数据到文本文件，怎么弄？

把你要保存的数据序列化一下，保存到文本中，如果需要修改，则从文本中取出，在反序列化化，在修改后，在序列化一下，保存到文本中。

文本的读写 参考fopen 等函数

Q4: php从文件中读取数据,保存到数组,从数组里选取前几列数据写入到文件里

?PHP

$file_name="1.txt";

$fp=fopen($file_name,'r');

$str=array();

$bian=0;

while(!feof($fp))

{

$buffer=fgets($fp);

$str[$bian]=$buffer;

$bian++;

}

fclose($fp);

var_dump($str);

$k=fopen("2.txt","a+");

for($z=0;$z2;$z++){

fwrite($k,$str[$z]);

}

fclose($k);
