PHP manual says that <code>preg_filter()</code> is identical to <code>preg_replace()</code> except it only returns the matches. So, you can use a combination of <a href="http://php.net/preg_replace" rel="noreferrer"><code>preg_replace</code></a> and <a href="http://php.net/array_diff" rel="noreferrer"><code>array_diff</code></a> to get results like preg_filter in PHP 5.2.x. Do it like this: <pre><code><?php $subject = array('1', 'a', '2', 'b', '3', 'A', 'B', '4'); $pattern = array('/\d/', '/[a-z]/', '/[1a]/'); $replace = array('A:$0', 'B:$0', 'C:$0'); $result = preg_replace($pattern, $replace, $subject); var_dump($result); //take difference of preg_replace result and subject $preg_filter_similar = array_diff($result, $subject); var_dump($preg_filter_similar); ?> </code></pre> This gives the output (with xDebug installed): <pre><code>array 0 => string 'A:C:1' (length=5) 1 => string 'B:C:a' (length=5) 2 => string 'A:2' (length=3) 3 => string 'B:b' (length=3) 4 => string 'A:3' (length=3) 5 => string 'A' (length=1) 6 => string 'B' (length=1) 7 => string 'A:4' (length=3) array 0 => string 'A:C:1' (length=5) 1 => string 'B:C:a' (length=5) 2 => string 'A:2' (length=3) 3 => string 'B:b' (length=3) 4 => string 'A:3' (length=3) 7 => string 'A:4' (length=3) </code></pre> Which is same as <a href="http://php.net/manual/en/function.preg-filter.php" rel="noreferrer"><code>preg_filter()</code> output</a>: <pre><code>Array ( [0] => A:C:1 [1] => B:C:a [2] => A:2 [3] => B:b [4] => A:3 [7] => A:4 ) </code></pre>

Guidance

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.
