Process PHP String value as Hashtag Markup with PHP

This page calls the hashtag_process Framework Core PHP function to process a PHP String value as Hashtag Markup.   The PHP String value includes another PHP block that calls the hashtag_process function again.   Hashtag Variable injection is not done until processing time.  
Processing this Hashtag Markup: 
<?php

$hashtag = '<?php ' .
	'$hashtag = \'<?php ' .
		'$hashtag = \\\'<# print "This was printed by Hashtag at <#[system.time]#>"; #>\\\'; ' .
		'hashtag_process($hashtag); ' .
		'?>\'; ' .
	'hashtag_process($hashtag); ' .
	'?>';	
hashtag_process($hashtag);

?>
Note:  This demonstration is beyond ridiculous.

The Hashtag Framework supports PHP code alongside Hashtag Markup.

The examples in this section demonstrate the many Hashtag Framework Core PHP Functions that are callable from any PHP code.
