→PHP fprintf formatting specifiers
<td>%X<td>Hexadecimal number in uppercase letters</td>
</table>
before we look at the fomratting options for we first need to see some of the above rules in action. Let's begin by embedding a string variable into a PHP fprintf function call:
<pre>
<?php
$myString = "Green";
$formatted = fprintf ("My favorite color is %s.", $myString);
echo $formatted;
?>
</pre>
In the above example the %s will be replaced by the value of $myString to create a string wich reads:
<tt>My favorite color is Green.</tt>
