    <p>This PHP code below will take an image and add the word <strong>_thumb</strong> in between the filename and file extension </p> <p>This file is called up to 50 times on some pages to show user photo, please not I only linked to a full path image on another server for this example, the file path is usually pulled from a Mysql DB that stores the path to a users photo </p> <p>I am currently restructuring a lot of things on my site though and I am wanting to know if this is a bad way?</p> <p>I store a thumbnail image like this:<br> <strong>filename_thumb.jpg</strong> </p> <p>So on a page to view a thumbnail, I only have the path to the full size image and I must add the _thumb part into the filename before displaying the image to screen.</p> <p>Would it be better performance to do something like<br> <strong>t_</strong>filename.jpg </p> <p>The data that come from the database is like this:<br> user/photos/1/23/45/34/filename.jpg </p> <p>So if I changed where I add the thumb part to the fron of the name would it still have to run all the code below to get a result? Please notice how the path I get from the DB is not JUST a filename it has the folder structure saved into it as well and the folders are always different.</p> <pre><code>&lt;?php $file = 'http://file-managers.net/skins/blue/images/actions/view_tree.png'; $fil_ext1 = pathinfo($file); $fil_ext = $fil_ext1['extension']; $fil_explode = '.' . $fil_ext; $arr = explode($fil_explode, '/skins/blue/images/actions/view_tree.png'); $pic1 = $arr[0] . "_thumb" . $fil_explode; // will show; // /skins/blue/images/actions/view_tree_thumb1.png echo $pic1; ?&gt; </code></pre>

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.
