15 Jan 09 PHP – Ternary Operator
I’m going to try and focus some time on building out the PHP section of the site now – here’s a useful technique, in shortening and tidying various cases of if/then/else.
This simply operates as:
$result = (condition) ? then : else
Consider the following code:
if (rand(0,1))
{
$result = “A”;
} else {
$result = “B”;
}
echo $result;
{
$result = “A”;
} else {
$result = “B”;
}
echo $result;
We can shorten this using the ternary operator:
$result = (rand(0,1)) ? “A” : “B”;
echo $result;
echo $result;
Or even:
echo (rand(0,1)) ? “A” : “B”;
For more information, see http://uk.php.net/ternary. This is supported in both PHP4 and PHP5
