/*
|
|
* The PH7 interpreter is a simple stand-alone PHP interpreter that allows
|
|
* the user to enter and execute PHP files against a PH7 engine.
|
|
* To start the ph7 program, just type "ph7" followed by the name of the PHP file
|
|
* to compile and execute. That is, the first argument is to the interpreter, the rest
|
|
* are scripts arguments, press "Enter" and the PHP code will be executed.
|
|
* If something goes wrong while processing the PHP script due to a compile-time error
|
|
* your error output (STDOUT) should display the compile-time error messages.
|
|
*
|
|
* Usage example of the ph7 interpreter:
|
|
* ph7 scripts/hello_world.php
|
|
* Running the interpreter with script arguments
|
|
* ph7 scripts/mp3_tag.php /usr/local/path/to/my_mp3s
|
|
*
|
|
* The PH7 interpreter package includes more than 70 PHP scripts to test ranging from
|
|
* simple hello world programs to XML processing, ZIP archive extracting, MP3 tag extracting,
|
|
* UUID generation, JSON encoding/decoding, INI processing, Base32 encoding/decoding and many
|
|
* more. These scripts are available in the scripts directory from the zip archive.
