This article discusses the setting of php.validate.executablePath in VSCode for remote CentOS. The author mentions that CentOS Linux will no longer be maintained and expresses the inconvenience of switching to a new system. They explain that they need to remotely edit and test some things by running them in Docker. They mention that although VSCode prompts them to set php.validate.executablePath, it doesn't seem to have any impact on their usage. They then try installing PHP separately on the host machine for VSCode. They provide instructions on installing PHP and checking its version. They also mention their confusion about CentOS's official SCL (Software Collections) and their attempt to install it. They provide instructions on installing SCL and searching for the appropriate PHP package. They install the package and verify its version. The article concludes without a clear resolution to the issue.

CentOS Linux is going to stop maintenance, but it's troublesome to switch..

I will remotely edit and test some things, and mount them into Docker for execution.

VSCode always prompts that php.validate.executablePath is not set, although it doesn't seem to have any impact afterwards.

I will try to install PHP separately on the host machine for VSCode.

# Install directly
yum install php

php -v
# PHP 5.4.16 (cli) (built: Apr  1 2020 04:07:17)
# ↑ The version is slightly lower

whereis php
# php: /usr/bin/php /usr/lib64/php /etc/php.d /etc/php.ini /usr/share/php /usr/share/man/man1/php.1.gz

Indeed, I don't quite understand:

{
"php.validate.executablePath": "/usr/bin/php"
}

I researched the official SCL of CentOS, but it doesn't seem to match my expectations.

# Install SCL (Software Collections)
yum install centos-release-scl-rh

# Search
yum search php
# rh-php73.x86_64
# ↑ Probably install this one

yum install rh-php73.x86_64

# List the libraries installed by scl
scl -l
# rh-php73

scl enable rh-php73 "php -v"
# PHP 7.3.29 (cli) (built: Aug  3 2021 12:26:40) ( NTS )

cd /opt/rh/rh-php73 && ls
# deregister  deregister.d  enable  register  register.content  register.d  root
