Php-mysql package for php 5.4.23 is conflicting Debuging line by line into the framework I now have found that the constructor at 1 level goes to initialize database() and finally it tries connection with mysqli_connect but I now see that my php5.4.23 generates undefined mysqli_connect()..wow! Now I'm trying to install php-mysql for php 5.4.23 but it gives
~>sudo yum -y php54 php-mysql
Error: php54-common conflicts with php-common-5.3.28-1.2.amzn1.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
FYI: php -v :5.4.23 ,mysql -v :5.5.34 ,httpd: 2.4.6 **CI:2.1.3, I'm debugging inside the core mysqli_driver now.(too risky but doing). Is it saying I dont have mysqli driver installed in my php package.
