How to add ... after end of string when using 'substr' in php?

I have text, for example:

$str = 'Hi there bla bla';

I used substr function for $str

substr($str, 0 , 20);

I got full text, but if I have longer text, lets say:

$str = "Hi there bla bla Hi there bla bla Hi there bla bla";
$substred = substr($str, 20, 21);

I thought I can use

if ($substred) { echo "..."; };

But it's not working .. ?

If you want it in an inline form using ternary logic

You can do it as follow:

$string = "Hey, Hello World"
strlen($string) < 10 ? $string : substr($string, 0, 10) . '...';

output: Hey, Hello...

This doesn't answer the question directly, but may be useful if the string is meant to be displayed via HTML. It can be done in CSS by using the style property text-overflow with a value of ellipsis.

  1. Always chceck, if your string you want to strip has this 20 chars to prevent disasters
  2. If you do check, you may easily add condition to add ... to your string

Code:

if (strlen($string) > 20) {
   $string = substr($string, 0, 20) . "..."; }

im assuming you want to echo a text but only part of it if it's too long and add "...". this might work..

if (strlen("$txt")> 20){
   echo substr($txt,0,20)."...";
}

Is this what you're looking for? You should probably count it first, then echo the result. http://codepad.org/OFo6MG6P

<?php
$str = 'Hi there bla bla';
echo 'Original: "'.$str.'", long one: "';
substr($str, 0 , 20);
$str = "Hi there bla bla Hi there bla bla Hi there bla bla";
$substred = substr($str, 20, 21);
if (strlen($str) > 20) { echo $substred."...\""; };
?>

You need to echo out the full statement with dots like this

$str = "Hi there bla bla Hi there bla bla Hi there bla bla";
$sentence = substr($str, 0, 21);
echo $sentence."....";
