Today, just to use bcadd () function, the result of an error, the next Baidu because there is no installation bcmath extension.
Then install chant, search for a moment, I was yum install php7.2, extensions can be installed yum
Ah, yum is really a great tool
Well, we started
1. Type the command (72W is the php version, there is a chance without an error)
yum install php72w-bcmath
carriage;
2.ok, the installation is complete, restart Apache or Nginx server on the list, you see playing is as simple as that!
ps: Of course, the proposal is still under server restart, restart Nginx for example, I have no effect, or restart Dafa good!
shutdown -r now # restart immediately
