这是我自己写的,但是只是可以读取出并且显示除了,不知道怎么插入数据库,而且TXT文件里面本来是有换行的,但是PHP读取出来都么有换行,还有一个问题就是如果用fread($data,1000)这个地方的是1000是指读取1000个字符,那如果需要一行一行的读取呢。现在这个TXT是一行一行这样的,如果说1000个字符这样子,那有可能最后只是读取到半行

<?php$data='11.txt';$files=fopen($data,"r");$res=fread($files,100000);echo $res.'<br>';


回复讨论(解决方案)

$data = '11.txt';$fp = fopen($data, 'r');while($r = fgets($fp)) {  $t = join("','", explode(' # ', $r));  $sql = "insert into 表 values ('$t')";  //.... 执行sql}


不过对于 mysql 似乎应该用 LOAD DATA INFILE 指令来完成

PHP code?1234567$data = '11.txt';$fp = fopen($data, 'r');while($r = fgets($fp)) {  $t = join("','", explode(' # ', $r));  $sql = "insert into 表 values ('$t')";  //.... 执行sql}

不过对于 mysq……

我按照你的这个,然后打开这个页面,直接不显示,空白的~

$data = '11.txt';$fp = fopen($data, 'r');while($r = fgets($fp)) { echo $t = join("','", explode(' # ', $r));  //$sql = "insert into 表 values ('$t')";  //.... 执行sql}




# 是不用插入到数据库里面的,另外如果这个文件很大,怎么分割呢

怎么样输出到PHP一行一行来显示呢,TXT默认换行是\n,这样的,PHP怎么匹配出来

你的数据不是按行按列(" # ")做值得吗?
只有你提供正确的数据和需求,才有可能得到可行的处理方案

$filename="11.txt";$fps=fopen($filename,'r');while(!feof($fps)){$ceshi=fgets($fps);echo $ceshi."<br>";}fclose($fps);


谢谢版主,我是按照这样的,然后浏览器输出以后就是和TXT文本一样显示出来了,但是如果要插入到数据库里面应该怎么做呢

我数据库里面有四个字段,id,name,time,bak

第一个是ID是auto_increment
其余三个字段都是varchar
现在TXT文件是格式是  
lisi # 121015 # 3900
xiaomao # 130205 #2500
lisa # 1258 # ok
我想插入到数据里面以后的数据是这样的
id    name     time    bak
1    lisi     121015   3900
2    xiaomao  130205   2500
3    lisa     1258     ok




我没有弄错,列分隔符是“ # ”,即 # 号两边各有一个空格(真难为你了,不嫌烦吗?)
补上字段列表,为
$t = join("','", explode(' # ', $r));
$sql = "insert into 表 ( name, time, bak) values ('$t')";

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
