First of all, sorry for my bad English.
I’ve been using free service from 000webhost for almost a year, from last month every mysql_fetch_assoc code are not giving any result.
My PHP version in cpanel already 5.5 but in phpmyadmin php version is 7.0.8 , is this causes my problem, How can I change php version in phpmyadmin databases.
The PHP version used by Database Manager doesn’t matter. The MySQL queries are the same.
Now you can run mysql_fetch_assoc() on your website ok, however I suggest you to move on mysqli_* functions, as mysql_* ones have been deprecated and removed as of PHP 7.
