Re: [Php-java-bridge-users] Stand alone execution of PHP (CLI script) through Java

[<php...@li...>]

Hi,

why don't you simply use an Ant exec task. The build.xml shipped with
the JavaBridge source code uses this, too.

You can use -Dphp.java.bridge.php_exec=/path/to/php-cgi.exe if php-cgi
is not in the PATH. Please see php.java.bridge.global.properties file
and our FAQ entry "How can I configure the bridge?"

Yes, please see PHP_EXEC_ARGS from the
php.java.bridge.global.properties file and our FAQ entry "How can I
configure the bridge?"

What are script-level arguments? Do you mean JSR 223 bindings? Please
see the JSR 223 specification for details.

(new ScriptEngineManager()).getEngineByName("php").eval("<?php exit(1+2);");

is just a glorified version of System.exec(...), as long as you don't
decorate the standard ScriptContext. So it isn't very useful for your
task.

It is the launcher.exe, encoded in 4 64k chunks (due to constraints of
the JVM). Please see target name="LauncherWindows" in
http://php-java-bridge.cvs.sourceforge.net/viewvc/php-java-bridge/php-java-bridge/build.xml?view=markup

That's a "honeypot" to make spammers happy.
