Google Starts Showing Real Time Search Results
Posted by Chris in Arb Stuff, Search Engine Optimisation on December 9th, 2009
You may notice Google has launched its latest enhancement to their search results… look carefully for a pause link and a scrollbar. These real time searches are live feeds from other large sites like Twitter. I have only seen Twitter so far in my result, but I believe that Google will show their news feeds and FriendsFeed too, plus a few more I am sure like Facebook and MySpace.
I did a search for “weight loss” and grabbed a screen shot for you…
Let us know what feeds you notice in the real time search results.
PHP: If Number Negative Then Make Zero
Posted by Chris in Tips & Tutorials on December 4th, 2009
In PHP, checking if a integer is negative and if it is then setting it to zero is easy, but I was looking for something shorter (and potentially faster) than:
if ($x < 0) $x = 0;
Well, this is a very quick check and reset, but there is a function max that does this too and it works with arrays too.
$x = max(0, $x); // $x will be set to 0 if it was less than 0
The max() function returns the number with the highest value of two specified numbers.
<?php
echo max(1, 3, 5, 6, 7); // 7
echo max(array(2, 4, 5)); // 5
echo max(0, 'hello'); // 0
echo max('hello', 0); // hello
echo max(-1, 'hello'); // hello
// With multiple arrays, max compares from left to right
// so in our example: 2 == 2, but 4 < 5
$val = max(array(2, 4, 8), array(2, 5, 7)); // array(2, 5, 7)
// If both an array and non-array are given, the array
// is always returned as it's seen as the largest?>
$val = max('string', array(2, 5, 7), 42); // array(2, 5, 7)
