Topic: [solved] PHP mbstring does not exist in Oracle Linux 7 repository

[dlemp]

Hello!

I'm trying to install the newest version of Mibew on Oracle Linux 7.  I'm using PHP 5.4.16.  I cannot, for the life of me, find the php_mbstring extension for this version of PHP!  I get the following message when going through the http://URLHERE/webim/install.php/install/check-requirements setup:


Follow the wizard to setup your database.

Correct the mistakes:
PHP mbstring extension is not loaded


Does anybody know how to either get the mbstring extension install, or get around this?

Thanks!

I mostly use Ubuntu linux, and I use the LAMP package which by default includes mbstring. I have not had to meddle with that manually, but my understanding is that the mbstring extension provides multibyte support. Don't think you can get around that since UTF-8 is a multibyte character encoding and by default most files are saved as UTF-8.

When I do a phpinfo on my system, I get the section shown below, which points that the mbstring extension is provided by the libmbfl library. This may be specific to ubuntu.

I believe Oracle Linux is based on the Redhat family (which also includes CentOS). I did some searching and came up with some links. Hopefully these point you the right direction.

Thanks for the reply and the links!  Everything you said and assumed is correct, and I was afraid that mbstring is necessary to use Mibew.  When I do phpinfo on my system, I have three lines that mention Multibyte, and all are similar to this one:

Zend Multibyte Support   disabled

I have tried to follow the info in the second link that you posted.  I was able to install php70u along with php70u-mbstring, but I could not get it to work with Mibew.  I'm not sure where the incompatibly lies (with Mibew, Apache, PHP, etc.) but something wasn't working correctly.  I would also like to keep with the current PHP version supplied by yum, it makes updates way easier.

I'll keep searching for a solution, I'm just not sure that there's one out there that will work for our situation.

Figured it out!  I found an updated CentOS php-mbstring that works with my Oracle Linux 7 install. 

It's on the page: https://www.rpmfind.net/linux/rpm2html/search.php?query=php-mbstring(x86-64)
