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>';
Copy after login

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


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}
Copy after login




# 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);
Copy after login


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')";

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
