phpMyAdmin gives export.php instead of database sql dump

问题

Environment

Wamp server 2.5 x64 (MySQL 5.6.17, phpmyadmin4.1.14) on Windows 10 Enterprise x64 (Fresh installation, no major changes since yesterday total installation)
Full control access to C:\wamp\tmp\ folder for windows everyone group, and the folder is not read-only

Problem

When I try to export my database using Export tab, under my database page, It gives me the export.php file, the body part of which is like this:

<body>
    <h1>phpMyAdmin - Error</h1>
    <p>export.php: Missing parameter: export_type&lt;a href="./doc/html/faq.html#faqmissingparameters" target="documentation"&gt;&lt;img src="themes/dot.gif" title="Documentation" alt="Documentation" class="icon ic_b_help" /&gt;&lt;/a&gt;<br /></p>
</body>

But, I expect the .sql dump file!

My effort

I googled for export.php: Missing parameter: export_type with no success.
I also visited http://localhost/phpmyadmin/doc/html/faq.html#faqmissingparameters for any useful notes, with no success.
In config.inc.php, the $cfg['PmaAbsoluteUri'] directive is empty.
In php.ini the arg_separator.input directive has value ;&.

I tried to use my browser's (Google Chrome 47.0.x.x) console to see If there is something wrong with it and I noticed this warning there:

Resource interpreted as Document but transferred with MIME type text/x-sql

Then I tried disable my browser's extensions one-by-one where I found this extension was the cause:

Free Download Manager Chrome extension (1.0.23)

I disabled it and now everything is fine.

I had a similar issue on a CentOS Cloud Server with Magento CE installed. My selection was to Export all tables, SQL format, Save to Output File, Add "Drop Table..", Add "IF NOT EXISTS". Instead of dropping a .sql file, it always dropped a "sql" file without any extension and regardless any filename I was choosing. Inside that "sql" file there was the html source of the current phpmyadmin page! I solved the issue by uncommenting and increasing the variable "max_input_vars" inside php.ini to 3000 rather than 1000. Hope this helps!

I suppose you are running http://localhost/phpmyadmin/export.php on Google Chrome. Switch to some other browser (Ex: Microsoft Edge) and then run http://localhost/phpmyadmin/export.php. Now export the database as usual.

I was trying to export my Magento database. And phpmyadmin instead of dropping a .sql file, retured a sql named file with no extension. Finally, I solved the problem by navigating to the php.ini file and uncommenting the "max_input_vars" variable and increasing its value. Don't forget to restart your xampp/wamp server after making the changes in php.ini.

Check up "Settings"(from main menu),then "Export" tab. "Save as file" checkbox should be checked.
When you setting up the export options, choose:
- "Custom - display all possible options" radio button instead "Quick".
- Set "Save output to file" radiobutton in "Output" section.
- Set "Format" dropdown box to "SQL".

Then press "Go" button.

I got same problem, but I solved it after increasing the Disk Space Usage of website.

I don't know your probblem will be solved or not but i solve by increasing Disk Space Usage

回答7:

Hi select custom display option when exporting database and uncheck option

Dump TIMESTAMP columns in UTC (enables TIMESTAMP columns to be dumped and reloaded between servers in different time zones)

This will resolve the issue.
