Variable handling Functions
PHP Manual

gettype

Get the type of a variable

Description

string gettype ( mixed $var )

Returns the type of the PHP variable var. For type checking, use is_* functions.

Parameters

var

The variable being type checked.

Return Values

Possible values for the returned string are:

  • "boolean"
  • "integer"
  • "double" (for historical reasons "double" is returned in case of a float, and not simply "float")
  • "string"
  • "array"
  • "object"
  • "resource"
  • "NULL"
  • "unknown type"

Examples

Example #1 gettype example

<?php

$data = array(1, 1., NULL, new stdClass, 'foo');

foreach ($data as $value) {
    echo gettype($value), "\n";
}

?>

The above example will output something similar to:

integer
double
NULL
object
string
