  1. I have a problem in the third step when I entered the code of PHP 7.3 then it shown the message command not found.

  2. Hey,

    Maybe a stupid question. But how can we start and restart PHP without rebooting the server?

    PHP 7.4.4 (cli) (built: Mar 17 2020 10:40:21) ( NTS )
    Copyright (c) The PHP Group
    Zend Engine v3.4.0, Copyright (c) Zend Technologies

    When we do [systemctl restart php74] results in Failed to restart php74.service: Unit not found.

    When we do [systemctl | grep php] not a single result is returned. Is php74.service not running? Or is it part of something else cause we installed it with the yum manager or something?

    Regards Jerome.

    • @Jerome,

      PHP is a just programming language that doesn’t have a service to start, you just need to restart the Apache or Nginx webserver to reflect changes you made to any configuration files of PHP.

      # systemctl restart httpd
      # systemctl restart nginx
  3. When running command : yum-config-manager --enable remi-php70

    this results, is this okay?

  4. Hey, how to Remove the PHP installed by this tutorial, I used this tutorial to install PHP 7.2 and now I wanted to remove it, It Not showing in Package On in ->

    $ which php
    $ whereis php
    php: /usr/bin/php /usr/lib/php /usr/local/bin/php 

    What is the Solution ?

  5. Hi,
    Thank you so much for your great article.

    I’m installing two PHP version 5.6 and 7, but when I enter php -v, it seems it only show 5.6. How can I use both of them?

    • @Vince

      You can only view one PHP version on the command line, which is the default version. But you can run different sites using different PHP versions, which requires some configurations.

  6. I have a question, I did this on my VPS to work with php 7.1 for laravel. After everything went good, all my wordpress websites got an 502 gateway error. I immediately got the backup restored and got my sites back, but now the PHP version is back to the old 5.6.3 which is to low for my laravel thing.

    Is there any solution?

    • @sonia

      You can run following command to remove PHP completely.

      $ sudo yum -y remove php*
      # yum -y remove php*

      Then install the PHP version you want to use.

  7. Thank you for your guides.

    You may want to clarify that this guide is for CentOS 7 without any PHP installed, and not an upgrade from PHP 5.4. Unfortunately, this article didn’t work for me, as I have CentOS 7.4.1708 with PHP 5.4.16 already installed.
