PHP new line every X characters in long characters sequence

How can I add a new line characters (\n\r) in txt file every 10 characters?

What I have is a long sequence of characters, and I like to create a new line for each 10 characters.

in example, let's say I have that sequence of characters:

FadE4fh73d4F3fab5FnF4fbTKhuS591F60b55hsE

and I like to convert it to that:

FadE4fh73d
4F3fab5FnF
4fbTKhuS59
1F60b55hsE

How can I do that ?

I know that I can use a loop for that, but because the above string is an example and my string that I have to split it is really very very long, just I wander if there is any faster and more easy way to spit my string.

As mentioned above, the use of chunk_split() might have unwanted consequences, as the break sequence is always added to the end once again.

You can instead use a combination of str_split() and implode() to first split the string every X characters and then recombine it with a break sequence. By using implode(), the break sequence will not be added to the end, again.

I've build a helper function who does this for me after 75 chars:

function createFold($s, $b = '\\n ') {
    $chunks = str_split($s, 75);
    return implode($b, $chunks);
}

using chunk_split():

$str = chunk_split($str, 10, "\n\r");

or using this regex:

$str = preg_replace("/(.{10})/", "$1\n\r", $str);

And by the way did you mean \r\n (New line in Windows environment) by \n\r? if so then the third argument for chunk_split() can be omitted.

<?php
$foo = '01234567890123456789012345678901234567890123456789012345678901234567890123456789';
$result = chunk_split ($foo, 10, "\r\n");
echo $result;
?>
