Increase import file size limit in phpmyadmin

Upload large size sql files in phpmyadmin :

1) Open file php.ini

2) Search parameters upload_max_filesize.

3) Increase the file size limit for the parameter.
Now you can upload sql files up to 512 MB in phpmyadmin.
In this example I have set limit 512 MB, you can set according to your requirement.

4) Increase file size limit for post_max_size and memory_limit too.
     It should be equal or greater than upload_max_filesize
post_max_size=1024M memory_limit=1024M

5) Restart Apache.

There is a instruction in php.ini that "Maximum amount of memory a script may consume (128MB)" but when you will increase the memory_limit size greater than 128M, you will see that you are not getting any error and large file has been uploaded successfully.

The first things to check are the values of upload_max_filesize, memory_limit and post_max_size in the php.ini configuration file. All of these three settings limit the maximum size of data that can be submitted and handled by PHP. post_max_size and memory_limit need to be equal or larger than upload_max_filesize.

Be careful to set memory_limit size. If it exceeds the limit, the phpmyadmin does not start. It shows blank page.

If you are not able to upload small size sql file (in-kb/mb) because of change in  memory limit. Make it again 128 MB and Restart Apache
