Support » Plugin: W3 Total Cache » W3 Total Cache > with PHP7 not working (mysql_connect)

  • It seems W3 Total Cache is not working with PHP7(.0.10), it does use mysql_connect which is deprecated and not anymore in php7 available. It needs to be upgraded to mysqli/PDO.

    It would be REALLY nice to have W3Total Cache for PHP 7 too. PHP 7 is 30%-70% fast than PHP 5.6 ;-)!

    thanks in advance

  • Actually, most of us here (those that frequent here regularly) are using a patched version of w3tc that is php7 compatible.

    Going one step further, others here are using a forked version maintained by one of the regulars here that merges many fixes to w3tc.

    For my contributions to the forked fixes i decided to use mysqli not PDO. The coding for it was much more one-to-one than PDO.

    Thanks for the hint, i did not recognize that there is a forked version which is better to use.

    Will try it out as described on your link, thank you.

    I was looking for information about W3TC stop working until I discover this post. Sad W3TC is not ready for PHP 7.
