Question

aside from doing the actual work of iterating through an associative array, pushing a value into a new array and setting that equal the array of remaining fields, is there an array function built into PHP that would do something like this?

if so, what is it?

i would be changing the following:

array(
    [0] => array(
        [created] => 12512512,
        [name] => something
    )
)

into something like this:

array(
    [12512512] => array(
        [created] => 12512512,
        [name] => something
    )
)

Answer 1

Flip the value and remove the old one in the same array… this should be fine provided the created value doesn’t overwrite one of the existing entries, which I highly doubt since created seems to be a timestamp.

foreach($myArray as $index => $entry) {
    $myArray[$entry['created']] = $entry;
    unset($myArray[$index]);
}

Or you could keep both copies and use references to save on ram.

foreach($myArray as &$entry)
    $myArray[$entry['created']] =& $entry;
