Why can't the php file be uploaded?

In the process of website construction, uploading files is a common operation, but sometimes we may encounter the problem of file upload failure, especially when uploading PHP files. This situation is usually due to server security reasons that restrict the upload of PHP files. So, how to solve the problem of PHP file upload failure? This article will introduce you to several solutions.

1. Modify the php.ini configuration file

One way to solve the problem of failure to upload PHP files is to modify the php.ini configuration file and change the upload_max_filesize and post_max_size values ​​to larger values. These two values ​​represent the maximum size limit for uploaded files and POST form submission data respectively. If the file size exceeds this limit, the upload cannot be successful. So, we can increase these two values ​​in order to upload the PHP file.

The specific steps are as follows:

1. Find the php.ini configuration file on the server. On Linux systems, the general file path is /etc/php.ini. On Windows systems, it is generally The \php.ini file located in the php installation directory.

2. Increase the upload_max_filesize and post_max_size values ​​appropriately, for example, change them both to 20M: upload_max_filesize = 20M post_max_size = 20M

3. Restart the Apache or Nginx server to make the modified configuration file take effect. .

2. Use FTP tool to upload PHP files

If modifying the configuration file in the above method cannot solve the problem, you can consider using FTP tool to upload PHP files. FTP is a standard file transfer protocol that can upload files from local to remote server. Typically, FTP tools upload files faster than other protocols such as HTTP, and are not limited by the server.

The steps to upload PHP files using FTP are as follows:

1. Use the FTP tool to connect to the remote server.

2. Open the website root directory of the remote server in the FTP tool.

3. Upload the PHP file to the website root directory.

4. Enter the URL address of the PHP file in the browser and you can access the file normally.

3. Compress the file into zip format and then upload it

If the uploaded PHP file is too large and may exceed the server limit, you can upload it through file compression. We can compress the PHP file into .zip format, then upload it to the server, and finally decompress the ZIP file.

The specific steps are as follows:

1. Compress the directory where the PHP file is located on the local computer into ZIP format.

2. Use the FTP tool to connect to the remote server and upload the ZIP file to the server.

3. Unzip the ZIP file on the remote server and place the PHP file in the root directory of the website.

4. Enter the URL address of the PHP file in the browser and you can access the file normally.

Summary: The above three methods can all solve the problem of failure to upload PHP files. If we encounter this problem, we might as well try the above methods. At the same time, in order to ensure the security of uploaded files, we should also strengthen the security settings of the server as much as possible to prevent the system from being affected by malicious attacks.
