Problema com tamanho de arquivo para upload

[zulian]

Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 6560263 bytes) in C:\ ... \Request.php on line 985

Como pode acontecer esse erro se estou dando limite maior que o tamanho do arquivo que estou fazendo upload. O codigo é esse.

<?php

ini_set("memory_limit","20M");
ini_set('post_max_size', '20M');
ini_set('upload_max_filesize', '20M');

Então cara,

Já tá :

memory_limit = 20M

; Maximum amount of memory a script may consume (20MB)

Ae setei no meu script só por segunça , ini_set("memory_limit","20M"); , mas nem assim .... Esse erro tá estranho , ele :blink: :blink:

Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 6560263 bytes) in C:\ ... \Request.php on line 985

:blink:

Erro fatal: Tamanho de memória permitido é 20MB (tentou alocar 6.25MB) em C:\..\Request.php

huuhuhhuuh

Alguma luz, pessoal?

[zulian]

Tipow eu limitei para 20M .

To fazendo o upload de +/- 7 M ele acusa esse erro ..

Se alguém puder ajudar pessoal :blink:

[zulian]

Bom dia pessoal ,

ninguém tem uma ideia ? ninguém sofreu com PHPTUBE

Aguardo. :blink:

[zulian]

E ae pessoal,

Consegui resolver o problema das mensagens de erros ...

Mas agora ele num da a mensagem de "UPLOAD COM SUCESSO !" ...

alguém pode me ajudar ... :wacko:

falou por enquanto pessoal ^_^
