PHP> echo string separated by lines of 3 words each? - arrays

Question

I need make something that includes a function that uses explode to create an array. I have seen several examples, but near the end I really get confused! Is there a simple readable way for this? (//comments?)
Take for instance a piece of text:
"This is a simple text I just created".
The output should look like this:
This is a
simple text I
just created
So the explode should split the text into lines of 3 words each.

Answer 1

$text = "This is a simple text I just created";
$text_array = explode(" ", $text);
$chunks = array_chunk($text_array, 3);
foreach ($chunks as $chunk) {
$line = $impode(" ", $chunk);
echo $line;
echo "<br>";
}

Answer 2

Try this is what you need:
<?php
$text = "This is a simple text I just created";
$text_array = explode(' ', $text);
$i = 1; // I made change here :)
foreach($text_array as $key => $text){
if(ceil(($key + 1) / 3) != $i) { echo "<br/>"; $i = ceil(($key + 1) / 3); }
echo $text.' ';
}
?>
Result:
This is a
simple text I
just created

Answer 3

Use substr() function link
Example:
<?php
$rest = substr("abcdef", -1); // returns "f"
$rest = substr("abcdef", -2); // returns "ef"
$rest = substr("abcdef", -3, 1); // returns "d"
?>
In your case:
<?php
$rest = substr("This is a simple text I just created", 0, 15); //This will return first 15 characters from your string/text
echo $rest; // This is a simpl
?>

Answer 4

explode just splits the string at a specified character. There's nothing more to it.
explode(',', 'Text,goes,here');
This splits the string whenever it meets a , and returns an array.
to split by a space character
explode(' ', 'Text goes here');
This splits only by a space character, not all whitespace. Preg_split would be easier to split by any whitespace

Answer 5

So something like...
function doLines($string, $nl){
// Break into 'words'
$bits = explode(' ', $string);
$output = '';
$counter=0;
// Go word by word...
foreach($bits as $bit){
//Add the word to the output...
$output .= $bit.' ';
//If it's 3 words...
if($counter==2){
// Remove the trailing space
$output = substr($output, 0, strlen($output)-1);
//Add the separator character...
$output .=$nl;
//Reset Counter
$counter=0;
}
}
//Remove final trailing space
$output = substr($output, 0, strlen($output)-1);
return $output;
}
Then all you have to is:
echo doLines("This is a simple text I just created", "\n");
or
echo doLines("This is a simple text I just created", "<br />");
..depending if you just want new lines or if you want HTML output.
