What is an important feature of the PHP scripting language?

PHP's Cross-Platform Nature: PHP originated for server-side web development, but also has a command-line interface (CLI) enabling its use for scripts and automation tasks.

Other Options:

Some languages are OS-specific (but less frequent with modern scripting languages) .

Many languages work in web or command line, not both like PHP.
