is_scalar

IS_SCALAR(3)								 1							      IS_SCALAR(3)

is_scalar - Finds whether a variable is a scalar

SYNOPSIS

       bool is_scalar (mixed  $var)

DESCRIPTION

	Finds whether the given variable is a scalar.

	Scalar variables are those containing an integer, float, string or boolean. Types array, object and resource are not scalar.

       Note

	      is_scalar(3)  does  not  consider resource type values to be scalar as resources are abstract datatypes which are currently based on
	      integers. This implementation detail should not be relied upon, as it may change.

       Note

	      is_scalar(3) does not consider NULL to be scalar.

PARAMETERS

	      o $var
		- The variable being evaluated.

RETURN VALUES

	Returns TRUE if $var is a scalar, FALSE otherwise.

EXAMPLES

       Example #1

	      is_scalar(3) example

	      <?php
	      function show_var($var)
	      {
		  if (is_scalar($var)) {
		      echo $var;
		  } else {
		      var_dump($var);
		  }
	      }
	      $pi = 3.1416;
	      $proteins = array("hemoglobin", "cytochrome c oxidase", "ferredoxin");

	      show_var($pi);
	      show_var($proteins)

	      ?>

	      The above example will output:

	      3.1416
	      array(3) {
		[0]=>
		string(10) "hemoglobin"
		[1]=>
		string(20) "cytochrome c oxidase"
		[2]=>
		string(10) "ferredoxin"
	      }
