                                   var_dump

   (PHP 3>= 3.0.5, PHP 4 )
   var_dump -- Dumps information about a variable

Description

   void var_dump ( mixed expression [, mixed expression [, ...]])

   This function displays structured information about one or more
   expressions that includes its type and value. Arrays are explored
   recursively with values indented to show structure.

     Tip: As with anything that outputs its result directly to the
     browser, you can use the output-control functions to capture the
     output of this function, and save it in a string (for example).

   Compare var_dump() to print_r().

   Example 1. var_dump() example
   <?php
   $a = array (1, 2, array ("a", "b", "c"));
   var_dump($a);
   ?>

   Output:
array(3) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  array(3) {
    [0]=>
    string(1) "a"
    [1]=>
    string(1) "b"
    [2]=>
    string(1) "c"
  }
}

   <?php
   $b = 3.1;
   $c = true;
   var_dump($b, $c);
   ?>

   output:
float(3.1)
bool(true)
