What is PHP and how is the programming language that has triggered a global cybersecurity alarm used?

PHP, a programming language powering 70% of websites, faces critical vulnerabilities discovered through AI. The PHP Foundation is working on security patches, but risks remain for many sites. Despite preventive measures, hackers could exploit these weaknesses, prompting urgent updates from web hosts. The vulnerabilities were identified during a security audit funded by OpenAI, marking a significant moment in cybersecurity. While major institutions can quickly update their systems, smaller sites may remain exposed, risking further exploitation.
