Splitting Text

[shogemuk]

Hi Guys,

does anyone know how split a text into groups depending on how many words are in the text

 

e.g

$text = "If you are new to PHP and want to get some idea of how it works, try the introductory tutorial. ";

I want a maximium of 5 words in each group, so the above text will be split as such

$text1 = 'If you are new to';

$text2 = 'PHP and want to get';

$text3 = 'some idea of how it ';

$text4 = 'works, try the introductory tutorial.';

 

But if I want a maximium of 10 words in each group, so the above text will then be split like this

$text1 = 'If you are new to PHP and want to get';

$text2 = 'some idea of how it works, try the introductory tutorial.';

$text3 = '';

$text4 = '';

 

 

Is this possible?

 

Please any help will be much appreciated thanks

from php.net http://www.php.net/manual/en/function.preg-split.php

 

<?php
/**
* Split a string into groups of words with a line no longer than $max
* characters.
*
* @param string $string
* @param integer $max
* @return array
**/
function split_words($string, $max = 1)
{
    $words = preg_split('/\s/', $string);
    $lines = array();
    $line = '';
   
    foreach ($words as $k => $word) {
        $length = strlen($line . ' ' . $word);
        if ($length <= $max) {
            $line .= ' ' . $word;
        } else if ($length > $max) {
            if (!empty($line)) $lines[] = trim($line);
            $line = $word;
        } else {
            $lines[] = trim($line) . ' ' . $word;
            $line = '';
        }
    }
    $lines[] = ($line = trim($line)) ? $line : $word;

    return $lines;
}
?>

sorry I misread that the $max is the length in characters not words

I just put this together and it works

<?php
$test = "this is a black dog walking down the road, he eats some food, he was hungry now he sleeps and has a dream of cats running in the backyard, what a crazy dog";
$parts = explode(" ", $test);
$i=0;
$k=0;
$num = array();
foreach ($parts as $part) {
if ($i == 5) { $i = 0; $k++; }
$num[$k] .= "$part ";
$i++;
}
foreach ($num as $res) {
echo "$res<br/>";
}
?>

dragon_sa thank you so much, that has solved my problem.  Thanks a lot

[dragon_sa]

here it is again as a function

 

<?php
$test = "this is a black dog walking down the road, he eats some food, he was hungry now he sleeps and has a dream of cats running in the backyard, what a crazy dog";
function wordSplit ($word,$count) {
$parts = explode(" ", $word);
$i=0;
$k=0;
$num = array();
foreach ($parts as $part) {
	if ($i == $count) { $i = 0; $k++; }
		$num[$k] .= "$part ";
		$i++;
	}
foreach ($num as $res) {
	$result .= "$res<br/>";
}
return $result;
}
echo wordSplit($test,5);

?>

 

This allows you to throw any string at it and set the number of words to split by
