Recreating an array from an array with only specific values.

[TitanKing]

Thank you for looking at this thread, I have a simple question which hopefully has a simple solution.

Ok, I want to create an array from an array, but the new array being created only with specific values. Almost like 'where' in mysql.

Example:

[0] => ("value"=>3)
[1] => ("value"=>2)
[2] => ("value"=>6)
[3] => ("value"=>3)
[4] => ("value"=>7)
[5] => ("value"=>8)
[6] => ("value"=>4)

Now I want to create a new array from above array where "value" = 3. I can do this through loops, I was just wondering if there are a better way of creating this without running through loops.

Thank you very much for trying to help out. :rolleyes:

Depending on what exactly you want to do, you might want to look at the array_filter() and array_keys() functions.

Ah, got it, thanks for the speedy reply, array_filter seems a bit heavy, however array_keys() is exacly what I am looking for. I should perhaps consider saving my arrays in a better way as well like so :

$test[]['test'] = 100;
$test[]['test'] = 200;
$test[]['test'] = 300;
$test[]['tester'] = 300;
$test[]['test'] = 400;
$test[]['test'] = 500;
$test[]['tester'] = 100;
$test[]['test'] = 600;
$test[]['test'] = 700;
$test[]['tester'] = 800;

    // Lets say I only want the array ['test']

foreach ($test as $value)
{
	print $value['test'] . "\n";
}

Am I correct in saying this ?
