    <p>I have two arrays.</p> <p>Example of the first array:</p> <pre> $arrayOne = array ( 'fruit' => array( 'apples' => array(), 'oranges' => array(), 'bananas' => array() ), 'vegetables' => array( 'tomatoes' => array(), 'carrots' => array(), 'celery' => array(), 'beets' => array ( 'bears' => array(), 'battlestar-galactica' => array() ), ), 'meat' => array(), 'other' => array() ); </pre> <p>2nd:</p> <pre> $arrayTwo = array ( 'frewt' => array( 'aplz' => array(), 'orangeez' => array(), 'bunanahs' => array() ), 'vetchteblz' => array( 'toem8ohs' => array(), 'careodds' => array(), 'sell-R-e' => array(), 'beats' => array ( 'bare z' => array(), 'tablestar-neglectia' => array() ), ), 'neat' => array(), 'mother' => array() ); </pre> <p>Notice that the two arrays are in the exact same "format" (same number of dimensions, number of keys, order, etc., etc.), only the names of the keys differ. (The array keys basically hold all the data.)</p> <p>I have a few variables that address the keys of the first array (<code>$arrayOne</code>). E.g. <code>$one</code> would address the first dimension of the first array, so it's value (string) would be one out of <code>'fruit'</code>, <code>'vegetables'</code>, <code>'meat'</code> or <code>'other'</code>.<br> <code>$two</code> would be <code>'apples'</code> or <code>'oranges'</code> or <code>'bananas'</code> or <code>'tomatoes'</code> or <code>'carrots'</code>, etc., you get the idea. (There's vars for each dimension)<br> As I said, those variables only address <code>$arrayOne</code>. I want to be able to address the keys in the second array too, though. Meaning, by looking at the value of <code>$one</code> I want to be able to get the array_key of both arrays.</p>

    1. COHow do you want to handle the case where an array key happens multiple times in the first array?

    2. COThat shouldn't matter, as identical keys will translate to the same keys in the second array. E.g. twice the key 'oranges' will be twice in the second array too, as 'orangeez'. I only really need the string of the appropriate keys of the second array.

    3. COOK, my solution stops searching after it finds the first key, but it's trivial to modify to return the positions for all the keys.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
