Why Are My Large File Uploads Still Failing Above 500MB?

Troubleshooting Large File Uploads Exceeding 500MB in PHP

Despite modifying PHP.INI configurations to support larger file sizes, you encounter challenges when uploading documents above 500MB. Let's explore potential solutions and considerations.

Consider Chunks for Optimal Upload Handling

While increasing upload size limits may seem like an obvious solution, it's crucial to consider the impact on memory usage. Attempting to upload massive files, such as 2GB, can strain server resources.

Instead of relying on increased upload limits, consider implementing a chunked upload mechanism. This involves dividing the large file into smaller, manageable chunks. Each chunk is uploaded independently, reducing memory requirements and enhancing upload stability.

Explore Additional Tips for Troubleshooting:

• Review your server's configuration for potential memory restrictions.
• Ensure that the server software (e.g., Apache, Nginx) is configured with adequate memory limits.
• Utilize server-side caching to optimize performance and reduce memory strain.
• Consider using an alternative PHP method for handling large file uploads, such as zip or gz libraries.
• Leverage tools or frameworks specifically designed for chunked uploads, such as Plupload or Flow.js.
