I'm working on creating a compiled extension for some code I've written. Mostly it's manipulating a very large multi-demensional array of values. This is some pseudo code for the array.

// Imagine this but much much bigger
$big_ass_array = array('5' => array('0' => 4, '3' => 6, '8' => 7), '10' => array('4' => 3, '5' => 10'));

Currently I'm traversing this with

foreach($array as $key1 => $value)
{
foreach($value as $key2 => $value)
{
// Use $key1, $key2, and $value here
}
}

My question is how does this translate into the C code I will have to write?

If anyone has a decent extension building tutorial that would be great too.

Regards,

-Josh

Well, I hope you are not using it this way.

The above will overwrite your $value variable set by the first foreach

Maybe you had a cut/paste error with the $value1 $value2 portion...

My suggestion would be to download the source code and find a comparable
array function and see how they do it.

First google result for "php extension tutorial"

Jim-

Yes, that was a typo. The issues was I didn't cut / paste and instead retyped it. Should be

foreach($array as $key1 => $list)
{
foreach($list as $key2 => $value)

I will check those links out, I had the first one not the second.

Regards,

-Josh
