PHP Get File Extension

Fire — Tue, 22 Nov 2011 13:47:37 +0000

Pathinfo does a number of things, depending on what we ask of it, but put simply it returns (path) information about a filepath. Full details can be found on the handy dandy pathinfo page in the PHP manual. Explore the PHP manual page when you get time, but for the purpose of this blog post I’ll hone in to one specific use of the function: getting the file extension. In order to do that, we simply call the function passing along the full filename and a ‘flag’ (a constant which dictates the behaviour of the function) asking for the extension only.

$filename = 'mypic.gif';
$ext = pathinfo($filename, PATHINFO_EXTENSION);

That’s all there is to it! In my opinion, this approach ‘reads’ much more easily than the mess of nested function calls and playing around with string positions, regular expressions, etc.. It is concise and to the point: call pathinfo and only give me back the extension. Simple.

Now for the icing on the cake. When pitched against the other methods detailed above, this call to pathinfo beats all of the others into submission. At least in my testing, it is the fastest method of all (though in random hiccups strrchr does win in around 1% of tests) being on average 1/10^th faster than even the strrchr approach.

WordPress wp_nav_menu Seperator And First Last Classes

Fire — Wed, 10 Nov 2010 19:42:23 +0000

Using WordPress wp_nav_menu function you can display navigation menus on your site nicely. You can even add the separators between each navigation menu. It can be done by passing these arguments either “link_before, link_after” or “before, after” to your wp_nav_menu funtion. However, you might face the problem with adding separators between each navigation menu.

Let’s say you would like to add “|” between navigation menu links but do not want to show it after the last menu.

e.g.
Home | About Us | FAQs | Blog | <– you do not want this

So far wp_nav_menu function does not add any additional classes to the first and last of the navigation menus. But don’t worry to much about that because there is a trick to fix it. Just copy and paste below code to your functions.php

Put this into your functions.php

function nav_menu_first_last( $items ) { $position = strrpos($items, 'class="menu-item', -1);

$items=substr_replace($items, 'menu-item-last ', $position+7, 0);

$position = strpos($items, 'class="menu-item');

$items=substr_replace($items, 'menu-item-first ', $position+7, 0);

return $items;

}

add_filter( 'wp_nav_menu_items', 'nav_menu_first_last' );

Put this into your style.css or any css file you using.

.menu-item-last {

display: none;

}
