Install Connection To Database Failed

[rbach]

We are trying to do a fresh install Zen Cart 1.5.4

When running the installer we are being given the error message 'Connection to Database failed'

Our Level 3 Tech Support spent a long time trying to solve this and reports as follows

(We should also say that we ARE able to install on a PHP5.3 server without issues)

We have double checked the database credentials being used as below by using the same credentials in a remoter MySQL client and this connects without issue

We have tried everything from changing between mysqli and mysql statements, triple checking the user/pass/database/hostname for connecting to MySQL server, to checking the error log for clues, all without having any success at getting ZenCart to connect.

When using my own test script that uses mysql_connect, there was no issue connecting, and I’m able to pull database data, as shown:

http://thesoapboxco.com/mysqltest.php

A similar test fails when using mysqli_connect:

http://thesoapboxco.com/mysqltestfail.php

This is why we had tried replacing mysqli statements in ZenCart code, but without luck getting it to work.

The error log indicates problems with PHP deprecated statements, including mysql/mysqli statements:

Based on this, we found the following article / posting:

==========================
http://stackoverflow.com/questions/1...ure-use-mysqli

“The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, is officially deprecated as of PHP v5.5.0 and will be removed in the future.

It was originally introduced in PHP v2.0 for MySQL v3.23, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

The manual has contained warnings against its use in new code since June 2011.

Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities."

==========================

Can you please confirm with the ZenCart developers that ZenCart is fully compliant with PHP 5.5.x, as it seems it is not?

You may need to stick with using servers that have PHP 5.3, as on web26, until the application is made compliant with PHP 5.5.×.

Please let us know if you need to migrate the ‘soapboxco’ account back to web26, and we can get that going for you, unless the developer has a way to fix the issue.

Zen Cart 1.5.2 and newer use mysqli_* (as you noted mysql_* is deprecated). I'm currently running a couple Zen Cart 1.5.4 sites under PHP 5.5.20 and 5.6.4 (with applicable patches).


Out of curiosity, what version of PHP and MySQL are in use on the site where you are experiencing issues?

Yes, Zen Cart v1.5.4 is fully compliant with PHP 5.5 ... AND it only uses mysqli_ functions not the deprecated/obsolete mysql_ functions.
