Custom php code in magento not working / magento block path wrong

i am new to magento & using magento 2 . I have to run a php code in my cms page . When i check the website i can understand that the theme is Alothemes Bencher6 . So what i did is

app/design/frontend/Alothemes/bencher6/Magento_Theme/templates

i create a new folder called myphp and file myphpcode.phtml insidethis folder .

So

app/design/frontend/Alothemes/bencher6/Magento_Theme/templates

there is two folder

1. html (this folder is there previously)
2. myphp (my custom folder )

in myphpcode.phtml i write the following code

<?php echo 'hiiiiiiiiiiii' ; ?>

Now i created a new page in magento and write the following code in content section

<block type="core/template" name="myphpcode" template="myphp/myphpcode.phtml" />

But for some reason this code is not working . I clear the cache . But still same . Please help
