The variable being type checked.

Return Values

Possibles 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(11.NULL, new stdClass'foo');

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

?>

The above example will output something similar to:
