Limit String Length

Question

I\'m looking for a way to limit a string in php and add on ... at the end if the string was too long.

Answer 1

You can use the wordwrap() function then explode on newline and take the first part, if you don't want to split words.

$str = 'Stack Overflow is as frictionless and painless to use as we could make it.';
$str = wordwrap($str, 28);
$str = explode("\n", $str);
$str = $str[0] . '...';

If you don't care about splitting words, then simply use the php substr function.

echo substr($str, 0, 28) . '...';

Answer 2

Do a little homework with the php online manual's string functions. You'll want to use strlen in a comparison setting, substr to cut it if you need to, and the concatenation operator with "..." or "…"

Answer 3

You can use something similar to the below:

if (strlen($str) > 10)
   $str = substr($str, 0, 7) . '...';

Answer 4

$res = explode("\n",wordwrap('12345678910', 8, "...\n",true))[0];

// $res will be  : "12345678..."

Answer 5

From php 4.0.6 , there is a function for the exact same thing

function mb_strimwidth can be used for your requirement

<?php
echo mb_strimwidth("Hello World", 0, 10, "...");
//Hello W...
?>

It does have more options though,here is the documentation for this mb_strimwidth

Answer 6

In Laravel, there is a string util function for this, and it is implemented this way:

public static function limit($value, $limit = 100, $end = '...')
{
    if (mb_strwidth($value, 'UTF-8') <= $limit) {
        return $value;
    }

    return rtrim(mb_strimwidth($value, 0, $limit, '', 'UTF-8')).$end;
}
