Set a constant in a php file to the value indicated.

This is a multi task.

This supports single or double quotes. Heredoc and nowdoc within the define are not supported. String constants are supported as are numbers, constants, and booleans. The quote marks will be maintained. So you can add quotes to transform from and initial number to a string. But, currently, you cannot transform a string to a number, etc. Grunt templates are supported in the config value field.

You can use one type of quote inside another, but escaping quotes is not supported.

So the following will work:

define('ENV','other "env"');


Example usage within grunt init:

    setPHPConstant: {
        stage: {
            constant    : 'ENV',
            value       : 'stage-<%="yyyy-mm-dd") %>',
            file        : 'temp/myfile.php'

The above would change the source of temp/myfile.php. It would change something like

define('ENV', 'blah');


define('ENV', 'staging-2012-11-30');

(Depending on actual date)
