    copied!<p>What i used:</p> <pre><code> $maxpoints = 40; for($i = 0; $i &lt; count($trainergross); $i++){ $trainergross[$i]['points'] = $maxpoints; $maxpoints -=2; } </code></pre> <p>heres my sort function:</p> <pre><code>function grossSort($gross, $compare) { if($gross['gross'] &gt; $compare['gross']) return -1; // move up else if($gross['gross'] &lt; $compare['gross']) return 1; // move down else return 0; // do nothing } </code></pre> <p>This is tricky (for me at least). I need to generate a points system based on the highest value gross degrading by 2.</p> <p>here is my array after running a function to sort it by highest gross (<code>$trainergross</code>): </p> <pre><code>Array ( [0] =&gt; Array ( [instr] =&gt; blah [club] =&gt; Colvin [gross] =&gt; 2146 [bud] =&gt; 0 [ratio] =&gt; 0 ) [1] =&gt; Array ( [instr] =&gt; rob [club] =&gt; Evans [gross] =&gt; 2000 [bud] =&gt; 0 [ratio] =&gt; 0 ) [2] =&gt; Array ( [instr] =&gt; new [club] =&gt; Boulevard [gross] =&gt; 930 [bud] =&gt; 755 [ratio] =&gt; 248 ) [3] =&gt; Array ( [instr] =&gt; test [club] =&gt; Boulevard [gross] =&gt; 805 [bud] =&gt; 50 [ratio] =&gt; 50 ) [4] =&gt; Array ( [instr] =&gt; lee [club] =&gt; Boulevard [gross] =&gt; 235 [bud] =&gt; 60 [ratio] =&gt; 30 ) [5] =&gt; Array ( [instr] =&gt; rob [club] =&gt; Boulevard [gross] =&gt; 175 [bud] =&gt; 125 [ratio] =&gt; 125 ) [6] =&gt; Array ( [instr] =&gt; rob [club] =&gt; Henrietta [gross] =&gt; 60 [bud] =&gt; 0 [ratio] =&gt; 0 ) ) </code></pre> <p>In this example <code>$trainergross[0]</code> should get a <code>key =&gt; value</code> of <code>"points" =&gt; 40</code></p> <p><code>$trainergross[1]</code> would get 38.. [2] would get 36... etc.</p> <p>I would then usort the array by bud, then do it again increasing the value key based on highest bud.</p> <p>My issue is, i dont even know where to start with doing this. Is it possible to add a key based on the order of the array?</p> <p>The only thought i have is doing 3 different arrays then merging them all, but that seems terribly inefficient.</p> <p>Sorry for vague, dont really even know how to ask, hopefully this explained it well enough.</p>
