gettype — Get the type of a variable

Description

Parameters

value

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"
• "resource (closed)" as of PHP 7.2.0
• "NULL"
• "unknown type"

Changelog

Examples

Example #1 gettype() example

`<?php

$data

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

foreach ( dataasdata as dataasvalue) {
echo gettype($value), "\n";
}?>`

The above example will output something similar to:

integer double NULL object string

`Be careful comparing ReflectionParameter::getType() and gettype() as they will not return the same results for a given type.

string - string // OK
int - integer // Type mismatch
bool - boolean // Type mismatch
array - array // OK
