How to format MySQL dates in WordPress using mysql2date

The mysql2date function is part of the WordPress core and is primarily used for formatting date and time. This function operates by converting a date or time from the MySQL format into a format that is more easily readable or usable by PHP.

One of the primary uses of the mysql2date function is in the retrieval of posts or content from the WordPress database. When content is stored in the database, the date and time are stored in a MySQL format. However, when retrieving this information for display or use in a PHP script, it may be necessary to have the date and time in a different format. The mysql2date function aids in this conversion process.

Additionally, the mysql2date function can be used to convert dates and times for other purposes, such as for use in calculations or comparisons within a PHP script. This allows for more complex operations to be performed based on the date and time of posts or other content.

The mysql2date function serves a key role in the handling and manipulation of date and time data within WordPress.

Parameters Accepted by the WordPress mysql2date Function

The mysql2date function in WordPress accepts three parameters. These parameters are as follows:

  • $format (string): This is a mandatory parameter which specifies the format in which the date should be returned.
  • $date (string): This is also a required parameter. It represents the date string which needs to be converted.
  • $translate (bool): This is an optional parameter with a default value of true. It dictates whether the returned date should be translated or not.

Return Value of the WordPress mysql2date Function

The mysql2date function returns different types of values based on the input parameters. If the $format parameter is either ‘U’ or ‘G’, the function will return an integer. In all other cases, the function will return a string. However, if the function fails to execute correctly, it will return false.
