array to many subarrays or something

kayelle

I'm stuck on this one. Hope you can help:

I have an array from mysql results something like:

$array = array(
these_comments =>comments,
these_image=>image,
these_rating=>rating,
these_measurements=>measurements,
something_comments=>more comments,
something_image=>another image,
something_rating=>another_rating);

I need to be able to separate the "these" keys and values from the "something" keys and values into new arrays like:

$these = array(
these_comments =>comments,
these_image=>image,
these_rating=>rating,
these_measurements=>measurements);

$something = array(
something_comments=>more comments,
something_image=>another image,
something_rating=>another_rating);

so I can resort the new arrays and display. Because the original array is a result from a mysql query, the number of possible elements is unknown.

I'd insert some sample code, but at this point I've made such a mess I wouldn't know what to show.

Thanks

try this

<?php
$array = array(
these_comments =>"comments",
these_image=>"image",
these_rating=>"rating",
these_measurements=>"measurements",
something_comments=>"more comments",
something_image=>"another image",
something_rating=>"another_rating"
);
echo "array[] is ";
print_r($array);
echo "<BR>";
$these = array();
$something = array();
$t_pos = count($these);
$s_pos = count($something);
foreach($array as $key=>$value){
	if(strstr($key,"these_")){
		$these[$t_pos]=$value;
		$t_pos++;
	}
	if(strstr($key,"something_")){
		$something[$s_pos]=$value;
		$s_pos++;
	}	
}
echo "these[] is ";
print_r($these);
echo "<BR> something[] is ";
print_r($something);
?>

Hi Kevin,

Thanks for the help. I think that will be useful for half of it. The remaining open issue is that unlike the array I provided as an example, the array I'm working with is filled with results from a form that are stored in mysql. The array could have up to 30 key groupings or just a few depending on which form fields the user will need. Eventually I'll be producing an inspection report and not all of the form fields are required for every product.

I tried using ereg to match similar keys by keys like
if (ereg("$key", $key)) {
, but since its in the foreach loop, they all match.

There must be some logic where I can loop through the original array, grab the group I need, put it in it's own array, reorder that array, display it, and then move on to the next grouping of keys in the original array.

Phew. Does that make sense?

Thanks
