PHP读取目录含特殊字符会变成?怎么将让MYSQL正确显示插入的UTF8编码数据
PHP读取目录含特殊字符会变成?,如何将让MYSQL正确显示插入的UTF8编码数据
123.txt文件编码UTF8,浏览器页面编码UTF8,Windows系统,代码页936
新建文件夹内只有一个文件夹,文件名为http://zhidao.baidu.com/link?url=9iTctYWxBKDqzxTH-QrBs5t6Q9lhRkutHCfJHaGRNlzsswkqWsnYLdtKfCk7F_AJQwMm2yxJmoOCLDGipSjr-a这里的爱心,CSDN不让直接发出来=。=
<br /><?php<br /> $path = iconv("UTF-8", "GBK", "F:/新建文件夹/");<br /> $dir = dir($path);<br /> $fopen = fopen("F:/123.txt", "a");<br /> <br /> while ($file = $dir->read()) {<br /> if ($file != "." && $file != "..") {<br /> $file = iconv("GBK", "UTF-8", $file);<br /> echo $file;<br /> //fwrite($fopen, $file));<br /> }<br /> }<br /> fclose($fopen);<br />?><br />
不论是echo输出在浏览器还是保存到123.txt中,都显示的是?。
1、我试过is_dir($path.$file);显示空,所以我估计这个问号不是显示问题而是read()时windows返回的就是ASCII的?,请问要正常读取应该如何解决?
2、另外要将UTF8编码的数据存储到MYSQL中,而且要求在MYSQL中不显示乱码,请问MYSQL中数据库、表和列的数据类型和排序类型应该如何选择?
谢谢!

这个与编码没有什么关系吧?

我看你的程序
1.$fopen没有使用到,创建的目的是什么?
2.is_dir($path.$file);显示空,因为is_dir是判断是否目录,而$path.$file是文件,因此返回false。
如果只是需要读出123.txt的内容显示,可以这样写。
<br /><?php<br />$path = iconv("UTF-8", "GBK", dirname(__FILE__).'/新建文件夹/');<br />$file = '123.txt';<br /><br />echo '<meta http-equiv="content-type" content="text/html; charset=utf-8">';<br />echo file_get_contents($path.$file);<br />?><br />
关键是 这句,设置页面编码。

2.如果要数据库保存不乱码,可以设置mysql
character_set_client:客户端来源数据使用的字符集
character_set_connection:连接层字符集
character_set_results:查询结果字符集
为utf8,
关于mysql 编码设置可以参考 http://blog.csdn.net/fdipzone/article/details/18180325

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query. If successful, a confirmation message will be output.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

To use MySQL stored procedures in PHP: Use PDO or the MySQLi extension to connect to a MySQL database. Prepare the statement to call the stored procedure. Execute the stored procedure. Process the result set (if the stored procedure returns results). Close the database connection.

Creating a MySQL table using PHP requires the following steps: Connect to the database. Create the database if it does not exist. Select a database. Create table. Execute the query. Close the connection.

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
