wp_convert_hr_to_bytes() │ WP 2.3.0

Converts a shortened byte value to an integer byte value. For example, the string 1Mb will be converted to the number 1048576.

Function workflow:

  • The passed value is processed through the functions trim() and strtolower().
  • The value is "cleaned" separately using the intval() function, discarding letters.
  • A check for the presence of characters such as g, m, and k is performed, based on which multiplication occurs.
  • The resulting value is processed by the min() function.

size_format() — a similar function that, on the contrary, converts the passed number (bytes) into a readable form, for example, 9999 will turn into 10 KB.

Used By: wp_max_upload_size()
