copied!<p>You can take advantage of the fact that PHP will dereference the results of a function call.</p> <p>Here's some example code I whipped up:</p> <pre><code>$x = 'x'; $y = 'y'; $arr = array(&$x,&$y); print_r($arr); echo "<br/>"; $arr2 = $arr; $arr2[0] = 'zzz'; print_r($arr); print_r($arr2); echo "<br/>"; $arr2 = array_flip(array_flip($arr)); $arr2[0] = '123'; print_r($arr); print_r($arr2); </code></pre> <p>The results look like this:</p> <pre> Array ( [0] => x [1] => y ) Array ( [0] => zzz [1] => y ) Array ( [0] => zzz [1] => y ) Array ( [0] => zzz [1] => y ) Array ( [0] => 123 [1] => y ) </pre> <p>You can see that the results of using <code>array_flip()</code> during the assigment of <code>$arr</code> to <code>$arr2</code> results in differences in the subsequent changes to <code>$arr2</code>, as the <code>array_flip()</code> calls forces a dereference.</p> <p>It doesn't seem terribly efficient, but it might work for you if <code>$this->x->getResults()</code> is returning an array:</p> <pre><code>$data['x'] = array_flip(array_flip($this->x->getResults())); $data['y'] = $data['x']; </code></pre> <p>See <a href="https://stackoverflow.com/questions/894814/deep-copy-of-php-array-of-references">this (unanswered) thread</a> for another example.</p> <p>If everything in your returned array is an object however, then the only way to copy an object is to use <code>clone()</code>, and you would have to iterate through <code>$data['x']</code> and clone each element into <code>$data['y']</code>.</p> <p>Example:</p> <pre><code>$data['x'] = $this->x->getResults(); $data['y'] = array(); foreach($data['x'] as $key => $obj) { $data['y'][$key] = clone $obj; } </code></pre>
