(PECL OAuth >= 1.0.0)

OAuthProvider::generateToken — Generate a random token

### Descrição

final public static string OAuthProvider::generateToken ( int `$size` [, bool `$strong` = false ] )

Generates a string of pseudo-random bytes.

### Parâmetros

`size`

  The desired token length, in terms of bytes.

`strong`

  Setting to `TRUE` means /dev/random will be used for entropy, as otherwise the non-blocking /dev/urandom is used. This parameter is ignored on Windows.

### Valor Retornado

The generated token, as a string of bytes.

### Erros

If the `strong` parameter is `TRUE`, then an `E_WARNING` level error will be emitted when the fallback rand() implementation is used to fill the remaining random bytes (e.g., when not enough random data was found, initially).

### Exemplos

Exemplo #1 OAuthProvider::generateToken() example

`<?php
$p = new OAuthProvider();
$t = $p->generateToken(4);
echo strlen($t), PHP_EOL;
echo bin2hex($t), PHP_EOL;
?>`

O exemplo acima irá imprimir algo similar a:

    4

### Notas

> Nota: When not enough random data is available to the system, this function will fill the remaining random bytes using the internal PHP rand() implementation.
