Description
print_r - Prints human-readable information about a variable
mixed print_r( mixed expression [, bool return] )
print_r() displays information about a variable in a way that's readable by humans.
Parameters
* expression
The expression to be printed.
* return
If you would like to capture the output of print_r(), use the return parameter. If this parameter is set to TRUE, print_r() will return its output, instead of printing it (which it does by default).
