IPB 4.2.5 : PHP 7.0 upgrade causes any problems ?

[Surendra.S]

Hi All,

I recently UPGRADED from IPB 4.1.17 to 4.2.5

During the upgrade, I got below message displayed on screen, but I completed the upgrade, as I had the minimum required PHP version.

You are running PHP version 5.6.19. While this version is compatible, we recommend version 7.0.0 or above.

You can re-run these checks later from the Support section of the Administrator Control Panel.

You do not have the Exif PHP extension loaded. While this is not required, it is recommended.

Just now, I have asked my server support team to upgrade PHP version on my server to PHP 7.0 and they replied that sometimes this can break sites when switching versions. 

I want to ask you below :

1) If I upgrade my PHP version to 7.0 now, will it cause any problem to my website running IPB forum ? Is IPB 4.2.5 fully compatible with PHP 7.0 ?

2) Whats the purpose of Exif PHP ? If it helps, I can get that installed as well, as I have a dedicated server. Please let me know.

Got a super quick reply from IPB support that IPB 4.2.5 fully compatible with PHP 7.0 / 7.1

Thank You !
