putting print_r results in variable
In PHP I can say:
print_r($var);
What I can't do (at least I don't know how) is:
$var_info = print_r($var);
How can I accomplish the effect of putting the results of a print_r inside a variable?
PHP v5.3.5
When the second parameter is set to TRUE, print_r() will return the information rather than print it
$var_info = print_r($var,true);
$var_info = print_r($var, true);
