break long string variable in multiple lines php [duplicate]

Question

I created a variable which stores a very long string, and I want to print this variable in multiple lines.

$test ="This is some example text , I want to print this variable in 3 lines";

The output of the above $test would be

This is some example text,
I want to print this
variabale in 3 lines

Note: I want a new line after each 15 characters or each line have equal characters. I don't want to add break tag or any other tag during variable assignment.

Answer 1

CODEPAD

<?php
$str=  'This is some example text , I want to print this variable in 3 lines, also.';
$x = '12';
$array = explode( "\n", wordwrap( $str, $x));
var_dump($array);
?>

or use

$array = wordwrap( $str, $x, "\n");

Answer 2

Try this

 <?php 
    $test ="This is some example text , I want to print this variable in 3 lines";
    $array = str_split($test, 10); 

    echo implode("<br>",$array);

Based on this link PHP: split a long string without breaking words

$longString = 'I like apple. You like oranges. We like fruit. I like meat, also.';

$arrayWords = explode(' ', $longString);

// Max size of each line
$maxLineLength = 18;

// Auxiliar counters, foreach will use them
$currentLength = 0;
$index = 0;

foreach($arrayWords as $word)
{
    // +1 because the word will receive back the space in the end that it loses in explode()
    $wordLength = strlen($word) + 1;

    if( ( $currentLength + $wordLength ) <= $maxLineLength )
    {
        $arrayOutput[$index] .= $word . ' ';

        $currentLength += $wordLength;
    }
    else
    {
        $index += 1;

        $currentLength = $wordLength;

        $arrayOutput[$index] = $word;
    }
}
