If you’ve ever encountered limitations on file size while working with PHP, you understand how frustrating it can be. In this extensive guide, we will explore strategies and techniques to boost the file upload size in PHP, ensuring the smooth and efficient operation of your web applications.
Understanding PHP’s File Upload Limitations
Before we dive into solutions, it’s essential to understand why PHP imposes file upload size restrictions. These limits are in place to prevent server overloads and enhance the security of web applications. While the default limits are generally reasonable, there are circumstances where you need to increase them.
Checking Your Current PHP Configuration
To begin, you should check your existing PHP configuration. This step is crucial because it helps you determine which limits need adjustments. You can do this by creating a simple PHP script:
<?php
phpinfo();
?>
Save this script with a .php
extension and execute it on your server. It will provide a detailed report of your PHP configuration, including file upload settings.
Adjusting PHP Configuration to Increase File Upload Size in PHP
With knowledge of your current limits, you can proceed to modify the PHP configuration. There are two primary methods for doing this:
- php.ini File Configuration Locate and open your
php.ini
file, which houses various PHP settings, including those related to file uploads. Look for the following lines:
upload_max_filesize = 2M
post_max_size = 8M
Adjust the values according to your requirements. For instance, you can change them to:
upload_max_filesize = 20M
post_max_size = 80M

Make sure to save the changes and restart your web server to apply the modifications.
To restart your Apache server use the below command.
sudo systemctl restart apache2
Verifying the File Upload Limit Increase
After making the necessary adjustments, it’s crucial to confirm that the file upload limits have been successfully raised. You can do this by creating a simple PHP script to check the current settings:
<?php
echo "Maximum File Upload Size: " . ini_get('upload_max_filesize') . "<br>";
echo "Maximum POST Size: " . ini_get('post_max_size');
?>
This script will display the updated values, verifying that your changes have taken effect.
Dealing with Common Issues
Increase File Upload Size in PHP is generally straightforward, but you may encounter some common issues:
- Server Resource Constraints If your server lacks sufficient resources, increasing the upload size can lead to performance problems. Consider upgrading your hosting plan or optimizing your code to reduce resource consumption.
- Security Concerns Allowing larger file uploads can pose security risks. Implementing robust validation and security measures to safeguard against potential threats is essential.
- Application Compatibility Ensure that your web application can accommodate larger file uploads without encountering errors. Thorough testing is vital to confirm compatibility.
