Google has announced the removal of the beta label from App Engine for PHP, with the service now generally available to all customers.

The beta version of the App Engine for PHP has been active for over a year, launching as the fourth scripting language available on Google's App Engine, alongside Python, Java, and Go.

Google App Engine is a platform-as-a-service (PaaS) offering from the search giant that enables users to build and run their own applications on Google's Cloud Platform.

In a blog post announcing the change, Google said the platform handles over 800 million PHP queries each week.

Last month, details emerged surrounding unpatched vulnerabilities in Google App Engine for Java.

The flaws were found by Polish security and vulnerability research company Security Explorations, which had previously received a reward of $50,000 from Google in response to finding approximately 30 security vulnerabilities in 2014. The research firm said that at least five of these weaknesses remain, with a Google spokesperson telling ZDNet that it is a known issue and the company is working on mitigating it.

Earlier this year, another flaw plagued Google Apps, with a fault in Google's Apps domain renewal system resulting in the exposure of over 280,000 hidden WHOIS records.

The bug was found by Cisco security researchers, and it took Google five days to fix and disclose the issue to those affected.
