/**
* Returns a parsable string representation of a variable.
* This method achieves the similar functionality as var_export
* but is more robust when handling arrays and objects.
* @param mixed $var variable to be exported.
* @return string parsable string representation of a variable.
* Exports a variable as a string representation.
*
* The string is a valid PHP expression that can be evaluated by PHP parser
* and the evaluation result will give back the variable value.
*
* This method is similar to `var_export()`. The main difference is that
* it generates more compact string representation using short array syntax.
*
* PHP 5.4 or above is required to parse the exported value.
*
* @param mixed $var the variable to be exported.
* @return string a string representation of the variable
