zulian

Pergunta

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
