+# PHP Explorations
+
+To build and run PHP programs on your local machine, download and install the most recent language version from the [PHP downloads page](https://www.php.net/downloads.php) or use your favorite package manager.
+
+Programs in this folder can be run from the command line like so:
+
+```
+php triple.php
+```
+
+```
+php permutations.php I like carrots           # NOT TESTED YET
+```
+
+```
+php top_ten_scorers.php < ../test/wnba_input           # NOT TESTED YET
+```
+
+Running the command `php -a` with no arguments gives you a repl.
+
+To run the tests on a Unix-like shell:
+
+```
+./test.sh
+```
+
+Run `test.ps1` in PowerShell.
