Categories UncategorizedTags PHP, phpMyAdmin94 Comments on Problem with phpMyAdmin and PHP 7.2: “Warning in ./libraries/sql.lib.php#613 count(): Parameter must be an array or an object that implements Countable”

It’s possible that when you installed phpMyAdmin, the version in the repository (phpMyAdmin v4.6.6) was not fully compatible with PHP 7.2. There is a newer version available on the official website (v4.8 as of writing), which fixes these compatibility issues with PHP 7.2.

This error is caused by a line of code in /usr/share/phpmyadmin/libraries/sql.lib.php. If you don’t want to wait for the repositories to update with the latest version, you can manually upgrade to the latest version of phpMyAdmin yourself.

Categories UncategorizedTags PHPLeave a comment on How to enable PHP short open tag (short_open_tag)?

PHP short open tags is deprecated feature of PHP and is strongly discouraged. It’s been recommended for several years that you not use the short tag “short cut” and instead to use the full <?php and ?> tag combination.

With the wide spread use of XML and use of these tags by other languages, the server can become easily confused and end up parsing the wrong code in the wrong context.
