Using ini_set("memory_limit", "-1") and still out of memory

Question

I'm processing an old database php array to a new database. The data .php files are in total around 220 MB large.

I've inserted these lines in the script so that it should run fine:

ini_set("memory_limit", "-1");
set_time_limit(0);

This is how I include the products:

// The exports made by PHPMYADMIN, exported as PHP-Array
require_once 'export/tx_ttproductsv2_products.php';
require_once 'export/tx_ttproductsv2_keyword.php';
require_once 'export/tx_ttproductsv2_keywords_in_products.php';
require_once 'export/tx_ttproductsv2_typebook.php';
require_once 'export/tx_ttproductsv2_typegospel7.php';
require_once 'export/tx_ttproductsv2_typemedia.php';

When the script is trying to require them I get this error:

PHP Fatal error: Out of memory (allocated 880541696) (tried to allocate 469762048 bytes) in ......

I've got an local EasyPHP installation running on x64 Win 7 SP1. I've got 6 GB memory, Intel i5.

How can I get PHP to run the whole script without the memory error?

Answer 1

Memory limitation comes from the OS, not from PHP itself.

Your script allocated 800MB and is trying to allocate further 500MB

Try to run the script on 64bit OS with 64 bit PHP.
