arrays - php var_dump() vs print_r() -


What's the difference between var_dump () and print_r () In the case of excluding an array in the form of a string?

var_dump function displays type and Structured information about variables / expressions including value Sorted values ​​are detected with the values ​​indented to show the structure. It also shows which array values ​​and object properties are references.

print_r () displays information about a variable that is readable by humans. The array values ​​will be presented in a format that represents keys and elements . Similar notation is used for the object.

Example: 

  $ obj = (object) array ('Quality point', 'technique', 'India');

var_dump ($ obj) will display the output below the screen. 

  object (stdClass) # 1 (3) {[0] = & gt; String (12) "Quality Point" [1] = & gt; String (12) "Techniques" [2] = & gt; The string will be displayed below the output in the string (5) "India"}

and, print_r ($ obj) screen. 

  StdClass object ([0] = & gt; Quality point [1] => Technology [2] => India)

But I do not think the code is capable of changing the color of each variable declared....
