Dynamically Created Array Names from Another Array?

[abilstein]

I have one array that I want to split into multiple arrays with array names and values based on the original array's elements. I am fetching the original array out of a database.

Let's call my original array "$myArray".

I could accomplish what I want by doing the following:

$col1[] = $myArray[col1];
$col2[] = $myArray[col2];
$col3[] = $myArray[col3];
$col4[] = $myArray[col4];

Later in the page I will access $col1[0] for a value.

I need the new array names to be based on the keys from the original array. My question is, can i do this with a loop somehow, dynamically creating the new array names based on original values? The reason being that I don't want to rely on hardcoding the new array names because there are a lot of them, and more importantly they may be changed elsewhere.

Is it possible somehow?

Not 100% clear on what you're after, but if you can get the names you want into an array, you can create variables with those names using the [man]extract[/man] function. That will give a bunch of variables named after the keys of the original array, with values matching the corresponding elements in the original array.

You can also just use $myArray['col1'][0] to get what you want. I would recommend that over extract.

You can use foreach on two-dimensional arrays as well. Like so:

foreach ($myarray as $key => $value) {
    // $key is col1, col2, etc. $value is the array.
    foreach ($value as $subkey => $subvalue) {
        // $subkey = 0, etc.
        echo "\\$myarray['$key']['$subkey'] == $subvalue <br />\\n";
    }
}
