PHP Shortcode 1.3

Based on kukukuan's Inline PHP, this plugin allows you to embed and run PHP code in posts, pages or widgets* with a WordPress shortcode.(* Requires a shortcode enabled widget plugin, such as Section Widget.)UsageThe plugin provides two pairs of shortcodes - [php]code[/php] and [echo]code[/echo]. these two pairs of shortcodes resembles the functionality of the and tags in a normal PHP script, respectively.For example:The answer to the ultimate math challenge, 1+2, is...[php] $a = 1; $b = 2; echo $a + $b;[/php]Will become:The answer to the ultimate math challenge, 1+2, is...3The [echo] tag will automatically print the returned value of the first expression. Therefore, [echo]some_function()[/echo] is essentially equivalent to [php]echo some_function()[/php].Some Important Notes** This plugin will change the priority of the do_shortcode filter. If you are experiencing any conflict with other shortcode plugins, please disable the plugin and report the problem in the forums. **Although I said the shortcode pairs resembles a tag pair, there is an important difference. The PHP code in the shortcodes are executed in a "throw-away" local namespace, instead of the global one. All variables defined in a [php] code [/php] block cannot be accessed outside the block. Therefore, this will not work:[php] $a = 1; $b = 2;[/php]The answer to the ultimate math challenge, 1+2, is... [echo]$a+$b[/echo]And neither would this:[php] $my_array = array('apple','orange'); foreach($my_array as $fruit):[/php]I like [echo]$fruit[/echo][php]endforeach;[/php]To work around the first problem, you may use the global keyword:[php] global $a, $b; $a = 1; $b = 2;[/php]The answer to the ultimate math challenge, 1+2, is... [php]global $a, $b; echo $a+$b[/php]And to work around the second problem, you may use "real" PHP closing tags within your [php] code [/php] block to switch between PHP and HTML mode:[php] $my_array = array('apple','orange'); foreach($my_array as $fruit):?>I like
