number_format_i18n Function Reference and Usage
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.
Usage:
echo number_format_i18n("4121124");
The output will display the number 4121124 in the correct localized format for your blog.
Lars, thanks for publishing this post. I hadn’t realised until today there was a function to easily take care of number formatting. The more discussion on it the better!
One correction, number_format_i18n can optionally take a second parameter – $decimals – representing the number of decimals to include.
