This guide helps administrators compare PHP versions and vendor updates using official sources. The reference records check times, distinguishes upstream releases from distribution backports, and marks uncertain states explicitly.
The checker only parses pasted text locally. It cannot verify a server or determine whether a compromise occurred. This site is not affiliated with the PHP project, foundation or PHP2Shell researchers.
