Split a string in half or insert into middle...

[mikka23]

Hi, I am not the greatest at PHP (no actual knowlege just look up when I have a problem).  I searched for this problem on google but didn't return anything which seemed efficient.  What I am trying to do is split a sentence into two or insert a </span> in the middle.

 

Its for a wordpress theme and I want the title of post to be like the following so the first half can be made a different colour:

 

<span>This is the</span> title splt

 

made from a string "This is the title split".  Does anyone know how to do this.  Help is greatly appreciated.

do you know exactly what the title is? or will it change?

You could use:

$num = strlen($title) ;

$num = $num/2;

 

$first_half = substr($title,0, $num,);

$second_half = substr($title, $num);

 

Something like that. Of course you might end up with a word changing colour midway.

Their are many ways to split the string, most will create an array then you just concatenate them back together,

but we need to know how you wish the split it up,

 

for example to split it in half you could do this

<?php
$str = "This is the title split";
$words = str_word_count($str, 1);
$first_half = ceil(count($words)/2);
echo "<span >";
for($n=0;$n<$first_half;$n++) echo $words[$n]." ";
echo "</span>";
for($n=$first_half;$n<count($words);$n++) echo $words[$n]." ";
?> 

 

or using word wrap

<?php
$str = "This is the title split";
$str = str_replace("\n","",$str); //remove linespace
$text = explode("\n",wordwrap($str, 20, "\n")); //word wrap at 20 char & put in array
foreach($text as $newtext){
echo "<span>$newtext</span>\n";
}
?>

Thanks for the replys guys.  Im trying them out now.  I think I would prefer to not split a word in half but if its a lot more difficult then I suppose it will do.

 

I tried out the first suggested code but I am getting an error on the following line (extra comma?)

 

$first_half = substr($title,0, $num,);

 

Thanks for the help guys, ive honestly never experienced such quick and helpful posts.

That's because your new here,

At PHPFreaks if you don't get a quick response then you probably asked the wrong question 

 

Oh and on that note welcome

 

EDIT: oh an my example don't split words

[mikka23]

I just tried your first example MadTechie, it seems just what I was looking for.  The only problem is getting the variable from wordpress (I though it was very simple).

 

<?php
$str = single_cat_title();
$words = str_word_count($str, 1);
$first_half = ceil(count($words)/2);
echo "<h2><span>";
for($n=0;$n<$first_half;$n++) echo $words[$n]." ";
echo "</span>";
for($n=$first_half;$n<count($words);$n++) echo $words[$n]." ";
echo "</h2>";
?> 

 

Now the problem is getting the category title into a variable (currently a function).  Im assuming Im doing something extremely stupid.

 

$str = single_cat_title();

[mikka23]

Sorry for the above post.  I worked it out.  For anyone wondering its just add the following:

 

single_cat_title("", false);
