Installation and testing of PHP 7 probes

First of all, this is a soft article, yes! It’s just a soft article. Because I know that "PHP is the best language in the world", I believe that many people are willing to read this soft article written by users, because this soft article should help students who develop PHP a little bit. We are a company that has been established for 7 years, so OneAPM's technical strength is recognized by the market and recognized by many users. Let's see how users use our products:

The following is a reprint of the content:

I originally thought that OneAPM did not have a PHP 7 probe, but when adding the application, I clicked on the "Update Log" and found that the PHP 7.0 probe had been released.

So I tested the installation right away.
Unfortunately, the installation failed with error message

NOTICE: PHP message: PHP Warning: PHP Startup: Unable to load dynamic library '/opt/remi/php70/root/usr/lib64/php/modules/oneapm.so ' - /opt/remi/php70/root/usr/lib64/php/modules/oneapm.so: undefined symbol: Z_BVAL_P in Unknown on line 0

Then I reported the situation to the engineer on Monday. After several tests, currently I didn’t encounter any problems, so I took some time over the weekend to describe my upgrade process.

First of all, remember to uninstall the old version of the probe before performing the following upgrade.

My environment is centos 7+nginx+php-fpm. I directly configured the remi source to upgrade PHP 7.0.0

<code>sudo yum install epel-release
sudo wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo rpm -Uvh remi-release-7.rpm
sudo yum install remi-release
sudo yum-config-manager --enable remi-php70
sudo yum update php\*
</code>

The above is to upgrade php. If you are installing it for the first time, you can run

sudo yum install php-common php-cli php-json php-pecl-memcached php-pdo php-opcache php-xml php-mbstring php-mysqlnd php-pear php-gd php-fpm

Then the installation of OneAPM Agent

After installation, restart php-fpm

sudo systemctl restart php-fpm

Run the following command to check the version of the probe

Wait for a while You can see your data in the database! Isn’t it cool? ? ?

However, my forum program is not good, and it inevitably uses a lot of eval

And many services rely on foreign servers. The domestic environment is really crazy

I think most of you are I installed Ai because I wanted to optimize the program, but I found that my response speed was much worse than others. I hope you can communicate more and share your optimization experience. Thank you in advance!
