PhpMyAdmin has no export as SQL option problem

Find the Export.php file in the phpmyadmin display folder or something like this phpMyAdmin/libraries/classes/Display depending on type of OS and package.

find the text /* Scan for plugins */ and put the code above right below after the text

if (isset($_GET['single_table'])) { 
$GLOBALS['single_table'] = $_GET['single_table']; 
}

Good luck

Error: Your requirements could not be resolved to an installable set of packages of composer

Solve by putting ignoring platform requirements

Example: composer require --prefer-dist victor78/yii2-zipper:"~0.0.4"

You will get error 

Your requirements could not be resolved to an installable set of packages. Installation failed, reverting ./composer.json to its original content.

So can by as follows: 

composer require --prefer-dist victor78/yii2-zipper:"~0.0.4" --ignore-platform-reqs
