split text into parts

Question

I wanted to split a large text into 10 pieces (somehow equal parts). Ii use this function:

<?php
function chunk($msg) {
   $msg = preg_replace('/[\r\n]+/', ' ', $msg);
   //define character length of each text piece
   $chunks = wordwrap($msg, 10000, '\n');
   return explode('\n', $chunks);
}

$arrayys=chunk($t);
foreach($arrayys as $partt){echo $partt."<br/><br/><br/>";}
?>

But is it possible to define word length of each text piece (not character length )? how to divide text into words in such situation?

Answer 1

I would suggest to use "explode" http://php.net/manual/en/function.explode.php for splitting the string by spaces. Then you'll get an array of words on which you can iterate and build your text-parts.

Answer 2

From docs,

<?php
$text = "ABCDEFGHIJK.";
$newtext = wordwrap($text,3,"\n",true);
echo "$newtext\n";
?>

OUTPUT: ABC DEF GHI JK.

Answer 3

You can do something like this. Breaks your text into equal parts.. The text in $str is of 20 chars, So the text is broken into 10 parts with 2 chars as a set.

Say, if your large text is of 1000 characters, then you will be getting 100 equal parts of text.

<?php
$div=10;//Equally split into 10 ...
$str="abcdefghijklmnopqrst";
print_r(array_chunk(str_split($str), (strlen($str)/($div))));

OUTPUT:
