How can we display information of a variable and readable by a human with PHP?

To display information about a variable in a human-readable format with PHP, you can use the print_r() function. The print_r() function is used to print the contents of an array or an object in a human-readable format. It can be useful for debugging or displaying complex data structures. For example, you can use print_r($array); to display the contents of an array. Another option is to use the var_dump() function, which provides more detailed information about a variable, including its type and size.
