WordPress Development Tip
In a previous post, I wrote about the usage of the date_i18n function in WordPress. This post will address how to properly format displaying values (numbers) according to the WordPress blog settings.
The function to use for this is number_format_i18n.
The usage is much easier than the date-function, as it is a simple function that accepts only a single parameter, the value to be displayed.
The output will display the number 4121124 in the correct localized format for your blog.
