# strval

(PHP 4, PHP 5)

strval — Get string value of a variable

### Description

string strval ( mixed `$var` )

Get the string value of a variable. See the documentation on string for more information on converting to string.

This function performs no formatting on the returned value. If you are looking for a way to format a numeric value as a string, please see sprintf() or number_format().

### Parameters

`var`

  The variable that is being converted to a string.

  `var` may be any scalar type or an object that implements the __toString() method. You cannot use strval() on arrays or on objects that do not implement the __toString() method.

### Return Values

The string value of `var`.

### Examples

Example #1 strval() example using PHP 5's magic __toString() method.

`<?php
class StrValTest
{
public function __toString()
{
return __CLASS__;
}
}
// Prints 'StrValTest'
echo strval(new StrValTest);
?>`
