The biggest conflict when using PHP Sessions has to do with the unique session identifiers. Because every user’s identification string is unique, this “busts cache” with every new user to visit your site. This kind of a system will not scale with many concurrent site users! With that in mind, our system specifically ignores headers defining a PHPSESSID cookie.Beyond the performance and scaling implications, PHP Sessions present other problems. By default, PHP Sessions store data to the filesystem as their own unique file. Writing data to a file is an I/O process, and these kinds of processes are known to back up and cause high server load if your site gets too many concurrent users. Not to mention, this kind of session storage simply doesn’t work if your site is on a clustered solution spanning multiple web servers.

WP-CLI’s mission is to be, quantitatively, the fastest interface for developers to manage WordPress. What does it mean to “unlock the potential of the WP REST API at the command line”? Pragmatically, it means any endpoints registered in plugins or themes are automagically accessible as WP-CLI commands. For instance, if you were to register an endpoint for GET /my-plugin/v1/product/, this endpoint is also accessible on the command line as (more or less) wp @prod product get .

The WordPress Way

The recommended way of passing data to JavaScript is by using the wp_localize_script function. This function is meant to be used after you enqueue a script using wp_enqueue_scripts.

Here’re the parameters:

• $handle. The handle to the enqueued script to bind the values to
• $objectName. The JavaScript object that will hold all the values of $arrayOfValues
• $arrayOfValues. An associative array containing the name and values to be passed to the script

After calling this function, the $objectName variable will become available within the specified script.
