Download WP CLI Temporarily & Using With Custom PHP Versions

Download WP CLI for Temporary Use

There are times when you log into the shell only to find out that the version of PHP WP CLI is outdated. Most common with cPanel mass hosting, they use a newer version of PHP for web and an outdated version for the CLI. Who uses CLI anyway? Well the pros do.

Ever Felt Stuck Finding No WP CLI Installed?

— Right When You Needed It The Most?

In the process of a WordPress Malware Cleanup, after having run a full scan and with a complete list of infections, we realized that this was a matter of quickly fixing all the malicious-files with a few WP CLI commands. WordPress core files were infected as was a huge list of infected plugins as well. Not having WP CLI meant hours of work, downloading the right version of plugins, extracting, overriding or uploading over FTP. Dang! There’s got to be a way to get this thing up and running instead of running under a site outage and downtime impacting visitors and affecting sales.

Wasn’t it possible to download WP CLI temporarily and use it?

It was. WP CLI is just another command-line tool that can be downloaded to any location, added to the path and the commands executed against any PHP version of your choice. Once you are done, delete and poof!

Make it easier to call

sudo mv wp-cli.phar wp

Remember the directory where you downloaded CLI.

Add WP-CLI to the path.

Using Custom PHP version with WP CLI

Want to use a custom version of PHP with CLI? Newer PHP versions are typically faster and way faster than PHP 5.6.

With phpinfo(); you can find the Configure Command options. Look for bindir. It will be something like:

bindir=/opt/cpanel/ea-php72/root/usr/bin

Set the WP_CLI_PHP environment variable to use your chosen php version.

export WP_CLI_PHP=/opt/php71/bin

If that doesn’t work, add this directory to your path and WP-CLI will use the newer PHP as long as you are in the same shell session.

export PATH=/opt/php71/bin:$PATH

WP CLI Change PHP Version Temporarily

/path/to/php//version/binary /path/to/wp-cli/binary

Example:

/opt/cpanel/ea-php72/root/usr/bin/php ~/public_html/wp-cli.phar <command>
