You can use the `header()` function in PHP to redirect the user to the `/e/admin` directory under the current domain name. You can retrieve the current domain name using `$_SERVER['HTTP_HOST']`, concatenate it with `/e/admin`, and then use the `header()` function to perform the redirection. Here is an example code snippet: `<?php // Get the current domain name...`

I have published a similar article before "PHP obtains the remote .sql.zip file, then clears the data, and then imports the .sql.zip into the mysql database", but here is another function that is also available for personal testing! 🔒 Hidden content: members can view /** * Download the ZIP compressed file containing the SQL file from the remote URL, decompress the SQL file to the specified directory, and then import the data to M…

You can use PHP's mysqli extension to operate the MySQL database. The following is a sample code to obtain the remote .sql.zip file, then clear the database, and then import the .sql.zip into the mysql database: &lt;?php // Set the MySQL database connection information $host = 'localhost'; $dbname = 'my_database…

The TRUNCATE command can be used to clear a table; however, if you need to clear an entire database, you must clear each table individually. Below is an example SQL statement for clearing an entire database: SET foreign_key_checks = 0; SELECT CONCAT('TRUNCATE TABLE `',table_name,'`;') FR...

This error message indicates that the database connection details you provided are incorrect when using PDO to connect to a database, resulting in a connection failure. Possible specific causes include: an incorrect database connection address (for example, the database address should be `localhost`, but you entered something else); an incorrect database name (for example, the database name should be `test_4s5_cn`, but you entered something else); or incorrect username or password (for example, the username should be `tes...`).

In PHP, you can use the `rmdir` function to delete a directory. This function removes the specified directory; however, if the directory is not empty, it cannot be deleted directly – the files and subdirectories within it must first be removed. Below is an example of using the `rmdir` function to delete a specified directory: $dir = '/path/to/dir'; // 要删除的目录路径 if (is_dir($dir)) {// If...

If your PHP environment does not have the ZipArchive extension installed, you may consider using a third-party PHP ZIP compression/decompression library, such as PclZip. PclZip is a pure PHP implementation of a ZIP compression/decompression library that is relatively easy to use. You should first download PclZip and then include the library file in your code using: require_once('path/to/pclz...');

The `tempnam()` function is one of the built-in functions in PHP, used to create a temporary file in a specified directory and return the path name of that file. Its function prototype is as follows: `string tempnam(string $dir , string $prefix)`. Here, the `$dir` parameter specifies the path to the target directory; if not provided, the system's default temporary directory path is used.

`sys_get_temp_dir()` is a built-in PHP function used to retrieve the path to the system's temporary directory. On most operating systems, there is a default system temporary directory, which is typically used for storing temporary files, temporary caches, and other temporary data. The `sys_get_temp_dir()` function returns the path to the temporary directory of the current operating system; this allows a program to use this directory for storing temporary files...

This error is usually caused by an error while downloading the remote ZIP file. You can check the following points: Confirm whether the link to the remote ZIP file is valid. You can try to open the link in the browser to confirm whether it can be downloaded normally. Confirm that the PHP environment has sufficient permissions to make network requests. You can use the PHP built-in function curl_init() to send network requests. You need to ensure that the PHP loop...
