How to Change the Maximum Upload file Size in PHP

What is PHP?

PHP (Hypertext Preprocessor) is a widely used server-side scripting language for web development. It allows developers to embed code within HTML files, enabling the creation of dynamic web pages and interactions with databases. PHP is known for its simplicity, versatility, and extensive integration capabilities with popular databases. It offers a broad range of extensions and has a large community of developers, ensuring ample resources and support.

How to change the maximum upload file size in PHP:

To change the maximum upload file size in PHP, you need to modify the following configuration settings:

Step 1

Open C drive with administrative access and then open xampp folder.

Step 2

Click on the folder php.

Step 3

Open php.ini file in editor mode (like Notepad or Wordpad) and Search for the upload_max_filesize directive. This determines the maximum size of an individual uploaded file. By default, it is usually set to a relatively low value like "2M" (2 megabytes).

Modify the value of upload_max_filesize to the desired size.

Step 4

Additionally, you should also check and modify the post_max_size directive. This setting determines the maximum size of the entire POST request, including the uploaded file. Search the post_max_size keyword and update its value to the maximum required value which is the size of the whole content and attachments included in the post.

It should be larger than or equal to upload_max_filesize. Update it to match or exceed the desired file size limit. For example, if you set upload_max_filesize = 100M, then you should set post_max_size = 100M as well.

Step 5

Save the php.ini file.

Step 6

Restart your web server for the changes to take effect. This step ensures that the new configuration settings are loaded.

After following these steps, PHP should allow file uploads up to the specified maximum size.

Conclusion

In order to change the maximum upload file size in PHP, you need to modify the php.ini configuration file. This file contains various settings for PHP, including the upload file size limits. By locating the upload_max_filesize directive in the php.ini file, you can adjust the maximum size of individual uploaded files. Additionally, it's important to also modify the post_max_size directive to ensure the entire POST request size accommodates the desired file size limit.

Once you have made the necessary changes in php.ini, it is crucial to restart your web server for the new configurations to take effect. This ensures that PHP recognizes and applies the updated maximum upload file size. Remember that different web hosting providers may have their own restrictions on file uploads, so it is advisable to check with your specific provider if you encounter any limitations.
