Type of a variable in PHP

Question

Have two questions -
1. How to find type of a variable in PHP.
2. How to find the type of an array in PHP.

Please help.

Answer 1

Use this:

http://php.net/manual/en/function.gettype.php

The nice thing about PHP 'arrays' is that they are a not restricted to a single type. The elements of an array can be different types. It's more a 'basket' than a traditional array.

Answer 2

How to find type of a variable in PHP.

gettype(), or one of the is_*()-functions. But for me more 
interesting for me: Why do you _need_ this?

How to find the type of an array in PHP.

An array is of type array :) is_array() or again gettype().

Can you maybe describe what you want to achieve? In a dynamically typed language it is rarely _required_, that you know the _concrete_ type.

Answer 3

 function get_type($var) 
 { 
    if(is_object($var)) 
         return get_class($var); 
     if(is_null($var)) 
         return null; 
     if(is_string($var)) 
         return string; 
     if(is_array($var)) 
         return array; 
     if(is_int($var)) 
         return integer; 
     if(is_bool($var)) 
         return boolean; 
     if(is_float($var)) 
         return float; 
     if(is_resource($var)) 
         return resource; 
     return unknown; 
 }
