Unsupported Historical Releases

We have collected all the official information and code available for past PHP releases. You can find more details on the current release on our downloads page. Please note that older releases are listed for archaeological purposes only, and they are no longer supported.

もうサポートされてなくて脆弱性もあるし危険だから普通には使わないでね！ってことか。
