How to solve the problem when installing php7 on mac but php5 exists

If you installed PHP7 on macOS system, but found the presence of PHP5 during operation, then this article will provide you with a solution.

First, we need to confirm that you have successfully installed PHP7. You can check the current PHP version by entering the following command in the terminal:

php -v

If you see the version information of PHP7, then you have successfully installed PHP7. But if you see the version information of PHP5, then you need to take the following steps to solve the problem.

1. Check the path

Enter the following command in the terminal:

which php

This command will display the path of the current default PHP version. If you see the path for PHP5, you need to change your path settings.

2. Change Path

Open a terminal and enter the following command:

sudo nano /etc/paths

This command will open a text editor to edit your path file. In the file you should see some paths, one per line. You need to add the path to PHP7 to this file, making sure it's on the first line. For example:

/usr/local/php5/bin
/usr/local/php7/bin
/usr/bin
/bin
/usr/sbin
/sbin

Note, before adding the path to PHP7, make sure the path already exists on your computer.

Save your changes and close the text editor. Now you can run the following command in the terminal for the changes to take effect:

source /etc/paths

3. Check Apache configuration

If you are using Apache as your web server, after installation After PHP7, you need to configure PHP7 in Apache. First, open the Apache configuration file. Enter the following command in the terminal:

sudo nano /etc/apache2/httpd.conf

Find the following line:

LoadModule php5_module libexec/apache2/libphp5.so

Comment out this line and add the following line to enable PHP7:

#LoadModule php5_module libexec/apache2/libphp5.so
LoadModule php7_module /usr/local/php7/lib/php/7.0/libphp7.so

Save your changes and close text editor. Now, restart Apache for the changes to take effect:

sudo apachectl restart

You should now be able to successfully install and use PHP7 on your macOS system without encountering the presence issues of PHP5. If you're still having issues, try restarting your computer and trying the above steps again.
