Split pages into two halves

Say I have a page of text attached to $page, so

$page = 'all my text in here for the whole page is written down by me in the most audacious fashion known to ferret-kind';

Code (markup):

Does anyone know how I can split it up into an $intro and a $main, so the $intro bit displays the first 10 words and the $main display everything but the first 10 words?

I tried doing a truncate type thing to get the $intro, then eregi_replace to remove the content of $intro from $page to make $main, but it didn't really work properly.

So I thought there might be a better way, any ideas?

 

Is this dynamic? If not, why don't you have 2 variables?

$intro = 'the intro text';
$main = $intro.' even more text!';

PHP:

or do something like:

$page = 'all my text in here for the whole page is written down by me in the most audacious fashion known to ferret-kind';
$splits = explode(" ", $page);
array_splice($splits, 10);
$intro = implode(" ", $splits);

PHP:

 

Yes it's dynamic.

 

OK, so the second did the work?

 

How would I create the $main part using your example?

 

Don't know how to get that wit array_splice, but use preg_replace instead;

$page = 'all my text in here for the whole page is written down by me in the most audacious fashion known to ferret-kind';
$splits = explode(" ", $page);
array_splice($splits, 10);
$intro = implode(" ", $splits);
$main = preg_replace("/$intro/i", "", $page);

PHP:

Tested it

 

Thanks, I will give it a try tomorrow. What is the /i bit for?

 

The slashes in the preg_replace functions as delimiter and the i to ignore case sensitivity. This whole process is called 'RegEx'. (Regular Expressions)

 

if you want to split text into multiple pages(dynamicly) I have the script for it.
by the way this is what you need:

<?php
$page = 'all my text in here for the whole page is written down by me in the most audacious fashion known to ferret-kind';
$splits = explode(" ", $page);
$count = count($splits);
$half = round($count / 2) ;
$arrayslice = array_splice($splits,0,$half,$else);
$firsthalf = implode(" ",$arrayslice);
$secondhalf = implode(" ",$splits);
echo $firsthalf;//firsthalf
echo "<br/>";
echo $secondhalf;//secondhalf
?>

PHP:

 

Thanks astrazone, I will try that too. I was just looking over my previous posts and realized I didn't reply to you.

 

substr(); is your answer!

$string = "ALL YOUR TEXT";
$start = 0;
$end = 10;
echo substr($string, $start, $end);

echo substr($string, $end, 6000);

Code (markup):

 

yuvrajm, that works too - I gave you a plus rep also.

Now if I could figure out how to make it so I can put code 10 in from the end instead of 10 characters from the beginning that would be uber cool.

 

Oh wait, just realized I already know the answer, just make the line $end = 10; into $end = -10;

 

This works really well, but how can I alter it it to count words instead of characters, or even just count white spaces so it doesn't chop words in half?

I know all the examples do that but this substr method seems the easiest so far.

 

got this solution from a website.
This $no will count words, but not whitespaces... for that you may simple make 2x of $no so whitespace may also be counted. I have not tested thus one till now.

function count_words($str)
{
$no = count(explode(" ",$str));
return $no;
}

Code (markup):

 

Great, but how do you achieve the same sort of thing as your first example using that?

 

Nope you need something like:

preg_match('#((?:\S+\s+){10})(.*)#s', $page, $matches);
$header = $matches[1];
$main = $matches[2];

PHP:

Good Luck!

 

Agreed! Actually I'm a little starter in regular expressions.

You are right, this is the best way to count chars in a string.

 

Well I can't even understand what that one's doing so I don't know how to get it to do the insert logo/ad thing after so many words?

 

What exactly do you want, just make a half of the page or make a complex query with multiple substr?
