When we use the server to configure the website, we pay more attention to the upload_max_filesize setting in the parameter configuration of PHP software. If the configuration is not good, the number of online users may not be enough. If the configuration is good, the load may be higher.
Upload_max_filesize is a PHP configuration item, which is used to set the maximum size of a single file that can be uploaded. Here are some tips for setting upload_max_filesize:
1. Parameter value
The value of upload_max_filesize can use bytes (for example, 100M means 100 megabytes) or other valid units (for example, K KB、M、MB、G、GB）。 Ensure that the appropriate units are understood and used correctly.
Edit the php.ini file: Find the php.ini file on the server and open it with a text editor. Search the upload_max_filesize configuration item, and set the required value after the equal sign. For example:
upload_max_filesize = 100M
2. Set appropriate file size limits
Set appropriate file size limits according to actual needs and application scenarios. Consider the type of uploaded files and the availability of server resources to avoid problems such as unstable services or resource exhaustion caused by too large files.
3. Restart the server
Save the php.ini file and restart the server to make the new configuration take effect. In this way, PHP will process the file upload request according to the new upload_max_filesize value.
4. Processing other related configuration items
The size of uploaded files is also affected by other related PHP configuration items, such as post_max_size and memory_limit. Ensure that these configuration items are consistent with upload_max_filesize to ensure a complete file upload process.
5. Consider security
When setting upload_max_filesize, you should carefully consider security issues. Ensure that the size of uploaded files is reasonably limited to prevent malicious users from abusing and server resources from being affected by too large files.
In conclusion, when we use a mature one click installation panel and software package, we will automatically set the initial value according to our server configuration. If we have subsequently adjusted the server configuration, we need to manually adjust some PHP parameter values.
