Get PHP MAJOR,MINOR and RELEASE Version Number – Linux Server

To find out the current version of php active on the server, there are basically two simple solutions and both use the php command with additional parameters.

1. php + grep + cut

@ php -v | grep ^PHP | cut -d' ' -f2
7.4.13

2. php +  internal constant from php itself

@ php -r 'echo PHP_VERSION;'
7.4.13

Other constants regarding the available PHP version are the following:

PHP_MAJOR_VERSION (int)
PHP_MINOR_VERSION (int)
PHP_RELEASE_VERSION (int)
PHP_VERSION_ID (int)
PHP_EXTRA_VERSION (string)

If you only want the version, without the last digit, you can use the following command:

@  php -r 'echo PHP_MAJOR_VERSION.".".PHP_MINOR_VERSION;'
7.4
