intdiv - Integer division

SYNOPSIS

       integer intdiv (integer	$numerator, integer  $divisor)

DESCRIPTION

	Returns the integer division of $numerator by $divisor.

PARAMETERS

	      o $numerator
		- Number to be divide.

	      o $divisor
		- Number which divides the $numerator

RETURN VALUES

	The  integer  division	of  $numerator	by  $divisor.  If $divisor is zero, it throws an E_WARNING and returns FALSE. If the $numerator is
       LONG_MIN (- PHP_INT_MAX - 1) and the $divisor is -1, it returns zero.

var_dump - Dumps information about a variable

SYNOPSIS

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

DESCRIPTION

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

	All public, private and protected properties of objects will be returned in the output unless the object implements a __debugInfo() method
       (implemented in PHP 5.6.0).

       Tip

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

PARAMETERS

	      o $expression
		- The variable you want to dump.

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      var_dump(3) example

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

	      The above example will 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);

	      ?>

	      The above example will output:

	      float(3.1)
	      bool(true)
