如何增加 phpMyAdmin 中的导入大小限制

Could you also increase post_max_size and see if it helps?

Uploading a file through an HTML form makes the upload treated like any other form element content, that's why increasing post_max_size should be required too.

Update : the final solution involved the command-line:

To export only 1 table you would do

mysqldump -u user_name -p your_password your_database_name your_table_name > dump_file.sql

and to import :

mysql -u your_user -p your_database < dump_file.sql

'drop table your_tabe_name;' can also be added at the top of the import script if it's not already there, to ensure the table gets deleted before the script creates and fill it

If you have direct root SSH access to the machine you will be able to change the settings in: /usr/local/cpanel/3rdparty/etc/phpmyadmin/php.ini

Just change the line: upload_max_filesize = 50M

If you are using WHM/Cpanel then in order to change that "Max: 50MiB" limit in the import section of phpmyadmin, you will have to change two values in WHM (Web Host Manager).

Step 1) Go to Tweak settings, find the "cPanel PHP Max upload size" change it according to your needs. Save changes.

Step 2) Go to Tweak settings, find the "cPanel PHP Max POST size" change it according to your needs. Save changes.

Go back to your phpMyadmin. The value should have changed.

if you're using xampp, find the php.ini (in xampp folder itself), go to line 735 and change the post_max_size to the value you wish. ex: if you want to upgrade to 80MiB,

post_max_size = 80M

make sure to restart apache after changing the value.

That's it...

I had the same problem. My .sql file was 830 MB and the phpMyAdmin import size allowed was 50MB (just as shown in the screenshot). When I zipped the file to .zip its size became about 80 MB. Then I zipped it to bzip2 format, and I was amazed to see that the file size was compressed to just 12MB (from 830MB to 12MB!!!). As phpMyAdmin allows three compression types i.e. .zip , .gzip and .bzip2 , therefore I uploaded the compressed bzip2 file and viola.... it was imported to the database!!! So by using the right compression, I was able to import a 830MB .sql file into phpMyAdmin.

NOTE: phpMyAdmin import page clearly instructs that the compressed filename should be like filename.sql.bz2 . It should not be like filename.bz2 .

NOTE 2: You can compress your .sql file to bzip2 compressed file using 7-Zip software. cPanel also has an option to compress a file to bzip2 format.

I had the same problem with my working correctly by doing the following

changes into the php.ini file

post_max_size = 800M
upload_max_filesize = 800M
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1000M

now restart for the changes to take effect

this is due to file size import limit in phpmyadmin, default is very low, so you should increase upload_max_filesize you can change this in your php.ini, replaced with this

upload_max_filesize = 100M

I increased the max file size by going to CPanel > Select PHP version > Switch to PHP Extensions and then scroll to the upload_max_filesize field (it will have a clickable link for the size - mine was set at 2MB) and I increased it to 256MB. Then click "Save".

Change these values in php.ini

post_max_size = 750M
upload_max_filesize = 750M
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1000M

Then restart Wamp for the changes to take effect. It will take some time. If you get following error:

Script timeout passed if you want to finish import please resubmit same zip file and import will resume.

Then update the phpMyAdmin configuration, at phpMyAdmin\libraries\config.default.php

/**
* maximum execution time in seconds (0 for no limit)
*
* @global integer $cfg['ExecTimeLimit']
*/
$cfg['ExecTimeLimit'] = 0;

You can increase the limit from php.ini file. If you are using windows, you will the get php.ini file from C:\xampp\php directory.

Now changes the following lines & set your limit

post_max_size = 128M
upload_max_filesize = 128M
max_execution_time = 2000
max_input_time = 3000
memory_limit = 256M

You Can Search php.ini file in C:\xampp\htdocs

changes into the php.ini file

post_max_size = 805M
upload_max_filesize = 805M
max_execution_time = 5005
max_input_time = 5005
memory_limit = 1005M

After editing Please restart XAMPP

1:nano /etc/php5/apache2/php.ini
you can find your php.ini location by uploading a file called phpinfo.php with the following contents<?php phpinfo();?> and access it by visiting yourdomain.com/phpinfo.php ,you will see the results

2:change the desired value to upload_max_filesize and post_max_size such as : upload_max_filesize = 200M post_max_size = 300M then it will become 200M.

3:restart your apache

First you have to change values in php.ini file as per your requirements.

post_max_size = 1024M
upload_max_filesize = 1024M
max_execution_time = 3600
max_input_time = 3600
memory_limit = 1024M

Note - Change these values carefully. These values will impact for all of your projects of that server.

Now, If above solutions are not working, kindly check your phpmyadmin.conf file. If you are using WAMP so you can find the file in "C:\wamp64\alias".

You have to change below values.

Values already in file are -

  php_admin_value upload_max_filesize 128M
php_admin_value post_max_size 128M
php_admin_value max_execution_time 360
php_admin_value max_input_time 360

Change above code to -

#  php_admin_value upload_max_filesize 128M
#  php_admin_value post_max_size 128M
#  php_admin_value max_execution_time 360
#  php_admin_value max_input_time 360

Now just restart your server, to work with changed values. :)

Change the file phpmyadmin.conf on c:/wamp64/alias/phpmyadmin.conf

php_admin_value upload_max_filesize 512M
php_admin_value post_max_size 512M
php_admin_value max_execution_time 360
php_admin_value max_input_time 360

It's very important you increase the time to 5000 or higher, Thus, the process will not stop when you are uploading a large file.

That works for me.

On newer version of cpanel: search ini

size' and edit it...then save[enter

Sharky's answer was spot on. The phpMyAdmin upload file size displayed is NOT managed by the php.ini settings, which you can see when you run a phpinfo.php containing:

<?php
// Show all information, defaults to INFO_ALL
phpinfo();
?>

It is good practice to increase your php.ini settings for:

post_max_size upload_max_filesize max_execution_time max_input_time memory_limit

You may use the settings example that Sujiraj R shared. Once you have made all of the changes to both your php.ini AND in the"Tweak Settings" area of WHM, when you launch phpMyAdmin and go to the import screen, you will see the size you selected for "cPanel PHP max upload size" field.

There were a lot of good answers on this post, but you had to look back and forth to get the right answer. I hope that by encapsulating those previous answers in this post I have helped just a bit. All of the answers I refer to on this post were derived by others that posted here, so please do not credit me with any of the answers posted herein.

go to your cpanel and search "ini editor". You'll get "Multiphp INI Editor" There you select your wordpress directory and put upload_max_filesize = 256M post_max_size = 256M memory_limit = 256M

Be sure you are editing php.ini not php-development.ini or php-production.ini, php.ini file type is Configuration setting and when you edit it in editor it show .ini extension. You can find php.ini here: xampp/php/php

Then

upload_max_filesize = 128M
post_max_size = 128M
max_execution_time = 900
max_input_time = 50000000
memory_limit = 256M

IF YOU ARE USING NGINX :

1. cd /etc/php/<PHP_VERSION>/fpm example => cd /etc/php/7.2/fpm

2. nano php.ini

   post_max_size = 1024M
   upload_max_filesize = 1024M
   max_execution_time = 3600
   max_input_time = 3600
   memory_limit = 1024M
   

3. after saving php.ini file , restart fpm using :

   systemctl restart php<PHP_VERSION>-fpm
   

example => systemctl restart php7.2-fpm
