In Chrome, if you run with the --enable-memory-info flag, you can get the data from:

console.memory;

which contains:

jsHeapSizeLimit
totalJSHeapSize
usedJSHeapSize

This data can also be fetched from a memory heap snapshot by pressing F12, but this is not programmatically.

You cannot read memory data using JavaScript code. A method to see the memory consumption is by inspecting the process.

Chrome has a built-in statistics screen, which can be summoned using Shift + Esc. This screen shows various information about each tab, including memory consumption.

You could format the PHP code with CSS & JS, but that's about it. Use the PHP Function, and HTML can't do that, it's just a markup language.

    <?php
    print(get_memory_get_peak());
    ?>

Try using the Task Manager, go to processes, and check the usage stats!

The Chrome developer tools include a heap profiler: http://code.google.com/chrome/devtools/docs/heap-profiling.html
