gettype

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

The variable being type checked.

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"

<?php

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

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

?>
