PHP eats a lot of memory on IIS

Question

Obviously the code below is too naive. How can an very large input be successfully compared with the largest int possible?

#include <stdio.h>
#include <limits.h>

int main ( void ) 
{
    unsigned long long input;
    
    printf("Enter a big integer: ");
    scanf ( "%llu", & input) ;
    
    if ( input > ULLONG_MAX ) printf ( " Too big!\n" ) ;
    else printf ( "%llu is not that big.\n" , input ) ; 
    
    return 0;
}

Solution

Windows Cache Extension for PHP

There seem to be a plethora of issues that revolve around the windows cache extension for PHP which sets hard memory limits for php.

There are examples and blog posts where removing wincache solves the issue but this may have a detrimental affect on performance of the site.

Managing PHP Memory in IIS

• php.ini - located in the root folder. Edit in TextPad and change the value for momory_limit. if 4M is not enough up to 8M, etc.

• In admin.php (if your error is in here) add a memory limit line after ini_set 'memory_limit', '12M' if 12MB of memory is what you're looking to add

• You can add a line to .htaccess: php_value memory_limit 32M

• wp-config.php can control memory. You put a line in that looks like this

  define('WP_MEMORY_LIMIT', '32M');
