How PHP restores print_r processed data to the original array

The PHP Print_r method allows you to print variables to make them easy to understand. If the variable is String,integer or float, the variable value itself will be printed, and if the variable is an array, the keys and elements will be displayed in a certain format. object is similar to an array. Print_r is used to print more arrays.

PHP native did not restore the Print_r method after the printed data to the original array, so write the following method, the implementation of the Print_r processed data to revert to the original array.
