Running PHP inside Wordpress Page

I need to run PHP inside a Word Press Page/Post WITHOUT use of an additional plugin or editing the WP code. Is it possible?

 

Display the code or actually execute it?

 

Well if you have access to php.ini (aka if you've got a VPS, or a dedicated server, or even just normal accounts for some hosts with custom control panels), you could use auto_prepend_file or auto_append_file (see http://www.php.net/ini.core at about half way down) to include a php file at the beginning or end of a page execution.

If you're on a typical host's shared hosting account with cpanel though, I'm pretty sure you won't be able to make a custom php.ini - in this case your best chance could be to put an include()/require() statement in a file that is always included (perhaps config.php, assuming you don't need any info about the page content from wordpress), requiring minimal change of the wordpress code. You could make a script to be run when a new wordpress version is installed, that adds an include statement to the bottom of config.php or any file like it. The script should look something like this:

<?php

$fileIncludePath = 'PATH TO FILE TO REQUIRE() IN MODIFIED FILE HERE';
$fileEditPath = 'PATH TO FILE TO CHANGE HERE';

file_put_contents($fileEditPath, '<?php require('.$fileIncludePath.'); ?>', FILE_APPEND) or die("Addition Failed!");

?>

PHP:

 

You shouldn't need access to php.ini. You should be able to do something like this in .htaccess:

<FilesMatch "\.(php)$"> 
php_value auto_append_file "/your/script.php"
</FilesMatch>

PHP:

This will only work if your host allows your .htaccess to overwrite the httpd.conf file.

 

Create a page template with your php code. (You can probably copy page.php or single.php and create a template from that.) Next on your post/page editing page, associate your template with that post/page.
