Allowed memory size of 16777216 bytes exhausted

[Jim Carlock]

I'm filling a really large array. Is there a way to get by
this error message without editing the php.ini? The array
needs to get built once, then looped through to fill a data-
base, and it will get alot bigger than 1.5MB, I'm going to
guess maybe at least 100MB.

[12-Sep-2007 11:41:53] PHP Fatal error: Allowed memory size
of 16777216 bytes exhausted (tried to allocate 10 bytes) in...
.... on line 23687

</snip>

The other thing I was thinking of involves using a function
that gets supplied an index and returns only 20 or 50 items
at a time.

Thanks for any comments/suggestions.

So, normally this would be perfectly changable in the script itself, in a
..htaccess or httpd.conf (for Apache), etc.

I'd look into possible solutions not even building your array, but a
straight insert (or update!) into the database. It depends on the actual
code/purpose though.

Thanks, Rik.

It took me a little while to find the appropriate function to set
the value. So to help others out, here's the function name and
use to help others reading along.

ini_set("memory_limit", "256M");

Interesting to see 'memory_limit' as a changeable setting via ini_set();

So, if a webhost set the PHP memory limit to 24M, and I know they have 2GB
on the machine, is it being suggested that I can override the limit set in
php.ini with a simple ini_set directive? This seems to put quite a lot of
'power' into the hands of PHP scripters?

Of course it is possible to prevent the value from being changed. If
settings were set with php_admin_value or php_admin_flag they can not be
changed.

And any descent host should know this.

Do you need to build the array? Are you building this array from a
file? If so why not format the file and do a LOAD FILE query or better
yet use PhpMyAdmin to upload your file. Not sure if you need to make
the array then upload from the array.

Any possibility we can see some of your code?

Well, it's easy to convert to a .csv format, but I don't mess
with PhpMyAdmin. I took a look at that once a while back but I
end up seeing too many hacks against it, which creates a rather
insecure feeling.

The array is easy enough to convert to a regular CSV file and
other database formats from that. No I don't need to build the
array. That's just the way it started out.

Thanks for asking. I won't have any code to show for awhile.
I'm just creating an array which will create a database. I
suppose I can get to know the file (line) reading functions of
PHP as another way to get this done, but that's not my interest
right at the moment. I'm playing around with big arrays.

I'm curious to others suggestions. I think I'll end up using
SQLite IF I get done with this.

// over 6000 API definitions...

// index, Win32APIFunctionName, ParameterList, ParameterListDesc, ReturnValue, ReturnValueDescSuccess, ReturnValueDescFailure,
Purpose_URI, Purpose_desc

return(array(
array(0, "AbortDoc", "(hdc:DWORD)", "plist_desc", "eSuccess:DWORD", "32-bit", "Upon success, the return value is greater than zero
(0).", "Upon failure, the return value is SP_ERROR.", "http://msdn2.microsoft.com/en-us/library/ms535758.aspx", "<p>AbortDoc() stops
the current print job and erases everything drawn since the last call to StartDoc().</p>\n<p><b>Windows NT/2000/XP:</bCall

I have PHPMyAdmin on several sites and never have a problem. They're
just in password protected directories so no one can get to them.

As for the hacks - just keep it updated, like everything else.

Or, you can continue to make things difficult for yourself. Your choice.

Or, are you confusing PHPMyAdmin (a web-based tool) with MySQL (a
database)? Again, I've had zero problems with MySQL on the systems I
have. But I have security in place, also.

Generally a sign of a poor implementation. Use a database.

I'd highly recommend MySQL or PostgreSQL over SQLite. Much more robust.

// over 6000 API definitions...

Purpose_URI, Purpose_desc

return(array(
array(0, "AbortDoc", "(hdc:DWORD)", "plist_desc", "eSuccess:DWORD", "32-bit", "Upon success, the return value is greater than zero
(0).", "Upon failure, the return value is SP_ERROR.", "http://msdn2.microsoft.com/en-us/library/ms535758.aspx", "<p>AbortDoc() stops
the current print job and erases everything drawn since the last call to StartDoc().</p>\n<p><b>Windows NT/2000/XP:</bCall
GetLastError() for extra error information.</p>"),

You definitely need a database.
