问题
is there a way native way in wordpress to make uppercase the first letter of the first word of the scentence / the_title of the post. If not how do I do it in php, while it is wrapped in a <a></a> tag. Here is the full line of code.
<a href="<?php the_permalink(); ?>"><?php ucfirst(the_title());?></a>
As you see I have tried the ucfirst but it does not work. The other thing that I tried is :
<?php
$temp_title = the_title();
$final_title = ucfirst($temp_title);
?>
<a href="<?php the_permalink(); ?>"><?php echo $final_title;?></a>
What am I missing ? Hope my explanation is clear. Please help.

ucfirst() returns a string. You need to echo the value returned from ucfirst().
Furthermore, the WordPress function the_title() prints the title directly, rather than returning it as a string. Use get_the_title() instead.
<a href="<?php the_permalink(); ?>"><?php echo ucfirst(get_the_title());?></a>

I think this is your problem: http://core.trac.wordpress.org/browser/tags/3.8/src/wp-includes/post-template.php#L51. As you can see the_title() is using get_the_title() and then if($echo) it echoes it out. I would experiment and try get_the_title().

First off you had an ending parantheses that didn't have a matching parantheses in your echo $final_title. Second you should try to apply ucfirst to the echo of your title. I removed $finaltitle, because it no longer serves a purpose. I haven't tried the code, but it should work. Please note that ucfirst() only works if the first letter is in the alphabet.
<?php
$temp_title = the_title();
?>
<a href="<?php the_permalink(); ?>"><?php echo ucfirst($temp_title);?></a>
